The Complete Zen Float Tent Water Maintenance Guide Plus A ‘Secret’ Tip To Prevent Water Trouble

float tank water maintenance 2

Are you excited by the thought of having a Zen Float Tent for a great floating experience right at your fingertips, but feel a bit intimidated by future costs and efforts that go with it?

Relax! It’s simpler than you thought! I have put together this summarized guide to make you fully prepared before your Zen Float Tent arrives.

First of all, here are the six aspects of your Zen Float Tent water maintenance you need to be aware of:

  1. Water levels (some of the water evaporates)
  2. Epsom salt levels (so you maintain your ability to actually float in the water)
  3. Ph and alkalinity levels
  4. Hydrogen peroxide application
  5. Filter maintenance and surface skimming
  6. Cleaning your tent.

Here is a step by step guide that will clarify each of these

To make it easier on you, I will divide these into initial, weekly, bi-weekly, and monthly tasks, so you can literally use this article as a reference point any time you feel confused as to what comes next. I will try to present it as a ‘recipe’ for water maintenance, so I will start with the ‘ingredients’ 🙂 Here are the

Must-Have Products For Your Float Tank Water Maintenance

  • 35% Hydrogen Peroxide (the primary disinfectant to prevent bacteria growth)
  • PH up and PH Down
  • PH and Total Alkalinity Test strips
  • Hydrogen Peroxide Test strips
  • Scum sponges to absorb oils in the water
  • A fine mesh marine skimming net

You will also have to test your water at a local micro biology lab every three months. Test for Heterotropic Plate Count and Total Coloform. Results of HPC should be less than 200CFU (Colony Forming Units) and the Total Coloform results should be zero.


  • Spray bottle with markings
  • Gloves
  • Goggles (to protect your eyes when cleaning the inside of the tent)
  • A headlamp (again for cleaning the inside of your tent)

Initial Set-up (When You First Install Your Zen Float Tent)

Once you install the Zen Float Tank into your house, you need to do a few things to make sure you’re off to a bacteria-free floating experience.

1st step is to wipe the walls of the tent with 10% diluted Hydrogen Peroxide.

This is where your spray bottle comes into play. Fill 10% of it with hydrogen peroxide, and the rest with filtered water (i.e. if your bottle holds 30 ounces, fill it up to 3 with Hydrogen Peroxide, and the rest with filtered water). Make sure you use gloves and goggles, since Hydrogen Peroxide is very corrosive, and you will want to protect your skin and eyes. Use the solution to clean your tent inside-out before you start using it. You will need to repeat this procedure every two weeks.

2nd Step is to get your water up to the necessary Hydrogen Peroxide levels.

This is absolutely critical, since Hydrogen Peroxide is a water freshener and an anti-bacterial agent, so it is the main ‘ingredient’ that will prevent bacteria and mold forming into your tank. The hydrogen peroxide concentration you need for this purpose is 40-60 ppm.

When you first fill in your tank, you will be at 0, which means it could take up to one gallon of 35% hydrogen peroxide to reach 50 ppm. You need to be using your test strips to determine when you have reached the required levels of hydrogen peroxide.

3rd Step is to test and adjust PH levels and alkalinity

Again, this happens with the help of your test strips and ‘Ph up’ and ‘Ph down’ products. All you have to do is put a test strip into the water and see what your acidity levels are. The Ph range you need is 7.2-7.8, while the alkalinity you need is 80-100 – these usually go together, so adjusting the ph levels will sort out the alkalinity as well.

If you need to increase the pH, put 1 tablespoon of pH up, then wait 30 minutes and test again.

If you need to decrease the pH, put 1 tablespoon of pH down, wait half an hour, and text again.

Sometimes alkalinity might adjust on its own (even if your pH is in the recommended range). When alkalinity is low, even though pH is in range, just add a tablespoon of alkalinity up (baking soda) to the water, wait 30 minutes and test again.

4th Step is to put a pool sponge into your water

This will absorb body oils and also assist in keeping the water clean.

Once you go through these initial steps, you just need to get into a maintenance routine:

Weekly Zen Float Tent Water Maintenance Tasks

  • Hydrogen Peroxide Levels
  • pH levels
  • Sponge washing
  • Skimming

You need to test Hydrogen Peroxide, pH, and alkalinity levels every week. Once you do the test with the strips, just add the necessary amounts of Hydrogen Peroxide and ph up or down.

The tricky part can be maintaining the Hydrogen Peroxide levels to 40-60 ppm – I like to keep them closer to the higher range in order to stay on the safe side when it comes to bacteria. As a guideline, when using 35% Hydrogen Peroxide, 1oz of liquid will raise the levels 5-20 ppm, depending on your current condition of the water in your tank.

Ph levels are pretty straight forward, and I’ve explained what you need to do in the initial step 3. Here is a video by Zen Float you can watch:

The other 2 weekly tasks are very simple too – you just need to rinse your pool sponge and use your skimming net to clean the water surface of any hair and dust.

Bi-Weekly Zen Float Tent Water Maintenance Tasks

  • Clean your tent

This is actually Step 1 of your initial set up. As I explained, get your spray bottle and prepare a 10% solution of diluted Hydrogen Peroxide. Using gloves, goggles, and a head lamp, get into your tent, spray, then wipe the walls with a rag. Do this even for the part of the walls which are under water as well as the outside of the tent.

3-4 Weekly Zen Float Tent Water Maintenance Tasks

This largely depends on how often you use your tank, but as you get in and out of it, water will evaporate, and you will be losing some of the salts as well. Therefore, you will need to be topping up the tank with water and Epsom salts every few weeks.

First, you need to top up the water to 10’’ preferably, using your water filter – this removes iron from the water and prevents water from yellowing. Here is a useful video by Zen float:

As far as salt saturation is concerned, again, this is important for your floating experience, as you want to float as much as possible. Zen Float have added a hydrometer, which makes it a simple task to check and adjust salt saturation. Here is a video explaining the process:

3-6 Month Zen Float Tent Water Maintenance Tasks

Every 6 months or so (depending on how heavily you are using your tank), you will need to change your filter bag. How do you know that you have to change it? By its light brown color – don’t let it get too dirty or you risk losing control over your water.

As I said before, all these are pretty straight forward once you get into the routine – remember it is much easier to maintain your water and tank clean than lose control over them, and have no choice but to change the water.

Finally, here is the ‘Secret Tip’ to preventing all water trouble with your Zen Float Tank

It’s actually a secret ingredient an early adopter (Nathan Snyder) discovered to keep the water extra clean and prevent the white mold from forming into the tank.

It’s Collodial Silver. This is basically ionized silver which is completely safe, and even used as a health supplement to treat infections, viruses and bacteria. Adding it to your tank will make sure your water stays extra clean. More on it in Nathan’s video:

As I said, if you follow these steps and clean your tank regularly, you shouldn’t be seeing any issues with your water. The tiny effort is worth the experience!

Happy floating!
