NoFlex VS Happy Campers: The Holding Tank Files Finale

ATTN: It’s kind of disgusting. Just saying.

I am finally getting back to our holding tank experiments, as promised. Alert readers with good memories will recall that we did a little product review on Zaal NoFlex Disgestor. We determined that it was very good at decomposing toilet paper, even in salt water, and we decided we’d be using this stuff all the time in our holding tank. In the comments section, one of our regular readers said that someone on his dock recommended a product called Happy Campers Organic Holding Tank Treatment. His neighbor claimed it worked just as well for less money. Hmmm. I like the idea of ‘less money’. Another reader said he appreciated our science experiment, but he was most interested in what the digestor did to ‘solid waste’. That is science code for ‘poop’.  It’s hard for me to resist these kinds of challenges. So between one thing and another, an additional experiment was born.

That's "Dr. Molecule", if you please.

That’s “Dr. Molecule”, if you please.

I purchased a container of the Happy Campers, got some supplies together, and tootled out to the Olympic Peninsula to the home of my sister, Amy. She is the mother of a 13 year old boy with an enquiring mind and a sense of humor. She also has a big dog. I needed both of those things in order to get this experiment off the ground.

My supplies:

1 container Happy Campers
1 container Zaal NoFlex Digestor
A bunch of brand new, unused plastic containers with lids
1 big container of sea water from the marina
Protective lab things like latex gloves, wigs, and lab coats.
A ready supply of dog poop.
Scientific measuring devices such as a food scale and our eyeballs.

The donor. Gonzo.

The donor. Gonzo.

The goal: To determine which holding tank additive works best to digest ‘solid waste’, i.e. poop. That’s right. We went there.

Method:  Since I was doing this experiment with my nephew and don’t want to be a bad science role model we tried to use the scientific method, sort of. We wanted to test the products with both salt water and fresh water. The fresh water is well water from Amy’s house, so there are no chemical additives. We set up 6 new plastic containers: two each for each product (one each for salt and fresh water), and two controls that would have only salt or fresh water but no product in them. We measured two cups of either salt or fresh water into each container and labeled them. Holes were punched into the lids to allow oxygen into the containers, just as our holding tanks are vented.

A bit too much.

We used 1.5 ounces of Gonzo poop for each container, weighing that out carefully. That was the most disgusting part of the experiment and offered plenty of opportunity for adolescent joking around. I’m talking about me and my sister, not my nephew. He’s way too mature and stoic to make dog poo jokes. We started this part of the experiment inside the house, but after opening the container of poo, thoughtfully collected by my sister before I arrived, we decided it was best to move it outside. I like doing experiments like this where other people have done the heavy lifting.

We initially decided we would add 1/4 teaspoon of each product to 2 cups of either salt or fresh water to see how the products responded. Deciding how to use the product was difficult because the directions are different for each one. Using the NoFlex requires that you add small amounts at a time to the tank. Using the Happy Campers requires that you add a scoop of the product to a gallon of water and flush that solution into the tank. It was a little bit like comparing apples and oranges but we needed to start somewhere, so the decision was made.fullsizeoutput_287

Results:

Adding the Happy Campers product to the containers resulted in little action right off the bat. The powder went in and dissolved and that’s pretty much it. After a few minutes some small bubbles began to form on the Gonzo poo.

Adding the NoFlex digestor to the water was vastly more entertaining. Immediately the Gonzo offering began to fizz and bubble in a most satisfying way. Interesting things were obviously beginning to happen. Within 20 minutes the largest piece of solid waste in the fresh water container was fizzing and floating near the top of the container. That’s probably more than you really want to know. Here’s the video. We get pretty excited and Amy uses a really long word.

The controls, both fresh and salt water with Gonzo poo added, sat there sullenly refusing to form bubbles or fizz or pretty much anything else. They were really boring.

At this point, I packed up my stuff and went home, leaving the experiment in the capable hands of my nephew and asking for a report back. They moved the containers inside to the table and then went to see a movie. When they got back, a few hours later, I got this text:

“Just got back from watching Miss Peregrine’s Home for Peculiar Children. The two with NoFlex are completely sludge on the bottom. Happy camper is mostly solid still. ”

Translation: Both the salt water and fresh water to which we had added the NoFlex had almost no remaining solids, only a layer of sludge on the bottom of the container. The Happy Camper’s had a thin layer of sludge but was mostly still solid waste.

About 7 hours of sitting and the NoFlex has taken care of most of the solids, even in salt water.

At this point in the experiment, the No Flex was clearly ahead of the game for sheer entertainment value as well as fast acting digestion of solid waste. But had we given Happy Campers a fair shot? Was our experiment designed well considering how different these products are?

Skippy, the unsuspecting donor.

I decided it was not, that Happy Campers deserved another shot at the win. This time I mixed up a proper solution according to the directions on the package. I didn’t bother with the salt water solution, just fresh. Since I do not have well water, I let the water sit overnight to dissipate chlorine. And I used our dog Skippy as a donor. The same amount of solution and poo was used.

The results were marginally better. After 24 hours, the solid waste was breaking down, but it was going to take its time doing it. Compared to the 7 or so hours the NoFlex took, this was a dramatic difference.

After sitting in the solution for 24 hours, there is decomposition, but still a lot of solid waste.

Conclusions: Both products will break down the waste in your holding tank, but based on this experiment, the Zaal NoFlex is going to work faster. I do not know how long it would take the Happy Campers product to break down the waste because I didn’t want to keep dog poo solution on my kitchen counter for that long. It’s gross. Perhaps the difference is kind of like the story of the tortoise and the hare. Slow but steady will get you there.  And you do need to add a small amount of NoFlex on a regular basis. Perhaps that’s where the cost saving issue with the Happy Campers comes into play.

For our purposes we’re still putting our money on the NoFlex, although we’ll keep the container of Happy Campers in reserve in case we run out of the NoFlex.  If there is any build up in the tank, the NoFlex will handle it, something the Happy Campers is not designed to do. In fact, they sell a different product on the Happy Campers website, designed to clean out the holding tank. Their website also makes the point that their product ‘lasts longer’ than any other product of its kind on the market. Perhaps that’s what we were seeing in our results. Maybe this product doesn’t work as fast, but it works longer.

That’s an experiment for another day. After all, research always brings up more questions than it answers. But I’ll leave you to decide if you want to go that far. And you’ll probably have to find your own 13 year old boy to help.

Studying up on the ingredients of these products and falling down the rabbit hole of research. Got to love a kid with an enquiring mind.

Preparing for Winter

Nine days.  That’s how much time lies between our warm, dry, comfortable home in Lakewood and living aboard a big drafty blue sailboat in the winter. We are feathering our floating nest preparing to move aboard during what is predicted to be a very cold winter in the Pacific Northwest. Brrr. It makes me cold just thinking about it, but here I sit in our cozy cabin, warm as toast.

Indoor temp is 77F. Toasty!

Indoor temp is 77F. Toasty!

Many of our land based friends wonder how we will keep warm on the boat during the winter. I wondered that, too, especially as the weather turns colder. It’s not a secret that I have decidedly NOT envied those liveaboards in our marina who are there year round. Nope. I did not envy them as I sat snugly in my sturdy energy efficient 1960’s rambler with all the thick insulation, double glazed windows and easy-to-adjust forced-air heat. I did not begrudge them their trip to the marina showers, and the hike back with wet hair wicking heat from heads hunkered against bitter wind. I did not yearn for that life style. But it is certain I will be joining them. Nine days and counting.

Move aboard, we will. This may not be the most cunning part of our plan, but it will do and it moves the plan forward considerably. After all, we have less than 6 months before we leave the dock!  I’m looking at this as an opportunity to learn to stay warm in creative ways. Galapagos was built in Greece. She is a warm weather boat. But if I am successful in not freezing my ass off and can learn to enjoy being aboard even if it’s cold outside, then maybe we could sail someplace like Norway or around the UK someday. Or even Ireland. A girl can dream.

Before I go on, I want to make the point that Mike does not suffer from cold as I do. Mike is the very definition of a warm-blooded mammal. Even when I know good and well that he’s cold just by looking at him, he says he isn’t. I’m not sure if he has that good a denial system, or whether his metabolism is, indeed, that impeccable. All I know is that when we go to bed at night, I’m the one using an electric blanket and wishing for a nice hot flat rock somewhere to lay in the sun and soak in the warmth. I’m the one with feet like small icebergs. I’m the one who wears fingerless mittens to bed so I can hold my hands up to hold the Kindle in fleecy comfort. Make what you will of that, but I’d appreciate your avoiding the term ‘reptilian’ when referring to me.

No, Mike does not suffer from the cold. He suffers from ME being cold. Because the day that I stop complaining about being cold one of two things will have happened: We will either be in Mexico, or I will be dying of hypothermia and be unable to speak. We’re not in Mexico yet. You do the logic. I owe it to him to continue to be cold out loud lest he think I am dying.

Sometimes wearing a wool cap inside makes all the difference.

No, Mike could be just fine living aboard in sub zero weather with only a hot water bottle to give him succor. So it’s up to me to consider my heating needs… All right, fine. Mike considers my need for heat, too, but I suspect much of that has to do with keeping my loud whinging down to a manageable level. Anyhoo, in anticipation of the longest and darkest night of the soul year, we’ve begun collecting our resources and putting plans into action in what we hope will not become “The Big Chill of 2017”.

Giving it some thought for this post, I realize it comes down to these things:

  1.  Keep the cold out.
  2. Create and keep warmth  inside.
  3. Wear a lot of clothing.
  4. Move around.

On Galapagos, keeping the cold out starts in the cockpit. We have that cockpit enclosure that, while on its last legs, is going to last us this one winter. That keeps the wind and water out of the cockpit very nicely and also creates a greenhouse effect, making that space warmer than the surrounding air.  It serves to keep the cold out, and it also serves to create heat.  So we start getting warmed up just by entering the cockpit.

Many of the things we are doing to keep the cold out serve the purpose of also keeping the warmth in. I’m referring to all the ways we are insulating the boat. Non skid bathroom rugs make fine insulation between feet and the cold cabin floor in the middle of the night. In the salon, I have cut a yoga mat to fit under the table and across to the starboard settee. It’s easy to sweep clean, colorful, and gives another layer of insulation against cold feet. You know, if the extremities of the body are cold, the rest of the body follows suit.

You can barely see the Frost King plastic around the edges here.

We lose a lot of heat through the ports and hatches because Galapagos has a ton of them. Some people block these with foam, but I do not want to block the life-giving rays of whatever weak and watery sun we get during the winter. To insulate the ports, I bought a cheap Frost King window insulation kit from Home Depot. It cost about 6$ and comes with plastic shrink wrap film and double sided tape. I taped all the ports after cleaning them well, then put up the window film, which is then shrunk tight using a hair dryer, effectively giving us double paned windows.  It’s a quick and satisfying project and will help reduce the amount of heat that escapes the ports.

For the clear overhead hatches, I’m planning to use big bubble wrap plastic, cut to fit the window, and secured with a little dab of caulk in each corner. We want to be able to open the hatches if necessary, and I’d like to preserve the light as much as possible.

That little fan on top of the stove is turning due to the heat. It works great.

As a source of heat we have a really nice diesel stove and a selection of small, efficient electric heaters. The diesel is our main source of heat. It actually works so well that it keeps most of the boat warm. If we close the forward and aft cabin doors, it really heats things up.  Mike says it’s so efficient that it must run on love because even leaving it going 24 hours makes barely a difference in the amount of fuel in the tank. The stove has its own 14 gallon tank that is connected by a series of valves and pipes to the main fuel tank. Right now we have 300 gallons of fuel aboard. We’ll be fine.

Even with the temperature hovering around 68 degrees in the cabin, the air can feel chilly when I’m just sitting around reading or seeing clients. So I keep our electic throws we bought at Costco spread on the settees in the salon. Turned on low, they create a little bubble of warm air, just enough to allow me to sit comfortably and write this post. On very cold nights, we can use them in the aft cabin for sleeping. At least I can. Mike probably won’t need one.

Sitting on the electric throw allows a bubble of warm air to surround you. Mmmm.

Sitting on the electric throw allows a bubble of warm air to surround you. Mmmm.

Even with plenty of insulation and heaters, it’s not like it’s summer inside the boat. We’re wearing clothing that we hope to mostly leave behind next spring. We’re talking wool. We’re talking layers. We’re talking entire polar fleece suits. We’re talking polypropylene long underwear. I’ve already mentioned my little fingerless mittens. Those are terrific. And there is no law against wearing a hat inside the boat. Keep the head warm, the feet warm, the hands warm. The rest is easy.

I think we have all these elements under control and we should be able to stay cozy during the cold winter months. The most challenging one will be ‘moving around’. That’s because unless I’m working on a project that requires it, being on the boat involves a lot of sitting. Mike’s daily routine won’t change that much because he still goes to work each day. I, however, work from the boat. Sitting around does not create much heat in the body. That’s bad on so many levels I don’t even know where to start.  I’m working on a plan for a new routine once we move aboard; a plan that involves getting off the boat every day; a plan that will keep my body moving around. I’ll let you know how that goes.

Post script: I’m adding a link to our brief discussion of our dehumidifier. I had a paragraph or two about this, but took it out because the post was too long. That led people to believe we didn’t have one. We love the Ecoseb unit. We moved it to the forward head where it drains its clean water directly overboard and is centrally located.

An Appointment With Adventure

Don’t get excited. We’re still at the dock. In fact, we are still going back and forth between house and boat so we have not yet escaped Tacoma. But we HAVE set the trapped spirit of Harry Houdini free by working through all the puzzles in a locked-room adventure called ‘The Last Escape‘. And we didn’t have to leave Tacoma to do it. If you don’t know why that excites us, then you haven’t been compelled to drive from Tacoma to Seattle.

‘The Last Escape’ is a puzzle room located in the very cool old post office building downtown in Tacoma on A Street, just up the street from the marina. Rather than buying a lot of useless stuff for Christmas we decided to give our family the gift of adventure and the anxiety implicit in having a time limit to unlock puzzles and codes. It works like this: You go into a room, the staff locks the door, and then you have 50 minutes to figure out how to get out. There’s a story line, and that makes it interesting, but that takes second place to the puzzles, codes, and mysteries you have to solve in order to get the clues you need. The clues lead to keys that go to locks and if you are successful in a ‘DaVinci Code’ sort of way, then you free yourselves, and, in this case, also the spirit of Harry Houdini, from the room. We managed to do it with 3 minutes to spare. Whew!

I have never participated in an activity like this, and frankly, the idea of being in a locked room with no way to get out for an hour filled me with a little bit of irrational dread. No bathroom? No food or water? I can live without food or water for way more than an hour. But if you tell me that I can’t use the bathroom for an hour, then I immediately have to go. Plus,  I kind of like my doors to open and close at my bidding. This would be outside of my usual comfort zone.

I was pleasantly surprised that I didn’t even worry about that locked door once inside because this puzzle room is so cool to look at that it took me right in. It’s staged like a Sherlockian 19th century library.  We were greeted by Madam Dana, a ‘medium’ who reads Tarot and is gifted with the ability to contact ‘the other side’. She begins by doing some Tarot readings (and yes, she really did read the cards!) and setting up the story line. Then she hangs around as part of the experience. Maybe she might also give a little tiny hint here and there as well, and a good thing, too because these puzzles are puzzling! The beginning minutes of the experience are like being cast in a play on a stage where only one character knows what’s going to be happening. I loved it and was disappointed that Mike was the only one who got to have his cards read. It was an uncannily accurate reading!

Our first puzzle involved looking for clues that would give us the secret code to unlock a special cabinet. After the first success, I was kind of hooked. This was way better than those cheap decoder rings we used to order from the back of cereal boxes! I’m not going to spoil the fun by telling you anything more about the room or its puzzles. But I am going to say that you should hurry and buy tickets for this before it’s discovered by all the hordes of puzzle lovers in the South Sound area. You buy your tickets on line for 25$ a person. There can be up to 10 people in the group, and you may be placed with other people if your group is smaller. We were pleased to have our group of 8 in the room to ourselves. The room is not large, and as you have to solve one puzzle at a time, 8 adults were plenty in the room.

This is Tacoma’s first puzzle room, but it’s not its last. Adventures By Appointment is working on a new room to be called “Red Scorpion: The Extraction.”  I’ll bet it’s also going to be great. In addition, they are working on a room to go along with the Tacoma Ghost Tour. This one will be historically accurate and it sounds like another winner. Tacoma could make a name for itself in puzzle rooms!
