Transcription of this episode… (in case you prefer reading)

Graham: Our question for today is: “lately, I’ve noticed small bubbles tickling me during my floats. They also seem to be forming on the floor of the tank. What is going on?”

Ashkahn: What is going on, huh?

Graham: Alright, well, “Bubbly in the U.S.” We’ve got a solution for you.

Ashkahn: We sure do. It sounds, to me, like you’re using hydrogen peroxide.

Graham: If I were to guess, I would say the same thing. Or, you’ve got an aerator hooked in to the bottom of your tank.

Ashkahn: Yeah. Which I suspect, it’s not the second one.

Graham: I’ve never seen that ever in my life before.

Ashkahn: Are you in a jacuzzi and not a float tank? Is that what’s going on here? Basically, hydrogen peroxide breaks down into oxygen and water when it’s reacting with stuff. If you have a lot of hydrogen peroxide in your float tank, you might start being able to actually notice those … the air being created from that breakdown process of the peroxide. That’s, basically, what you’re feeling. You’re feeling tiny, air bubbles from the hydrogen peroxide.

Graham: And, for us, we end up getting that effect in our float tanks when we get above or around 100 parts per million.

Ashkahn: Yeah, somewhere in that … like 100, 110. That’s the range where we start to notice the bubble issue.

Graham: That’s as measure by the old Taylor Drop Test Kit, K-1826.

Ashkahn: Which, has been verified to be accurate in float tank water.

Graham: Which, you can look up. Taylor Labs actually tested our float water after we harassed them for a long time. You might find that those parts per million are different if you’re using test strips, or something else. Also, if you are, I highly recommend switching over to the old K-1826.

Ashkahn: Basically, that. Just don’t put your peroxide to those levels. Drop lower than that, and you won’t see those bubbles.

Graham: And that said, I still, occasionally, get bubbles, even when we’re within regular hydrogen peroxide levels. But, it’s not bubbles tickling your back, I’ll just, occasionally, feel them forming on my back, or something came up and I just have one bubble that’s caught and tickling me. I don’t think that’s even that out of the ordinary.

Ashkahn: It’s way more subtle. This is almost continuous while you’re floating. You’re feeling these things, if your levels are too high.

Graham: If you bring it up to 400, 500 parts per million, accidentally, one of your staff drops way too much in there … sometimes, you can actually even see the bubbling in the water itself, visually, which is kind of interesting. Looks like little cauldron brew, or something, in there.

Ashkahn: So, don’t do that.

Graham: Another question, “Is that unsafe?” Are the bubbles a sign that your skin is being eaten by the hydrogen peroxide, or anything crazy like that?

Ashkahn: Not really, that I know of. The other thing that can happen with these levels of peroxide is, you can, very slightly, start to bleach people’s hair, which is another issue. Those are the main reasons people don’t want to go above these 100 limits. I don’t really know, I can’t really speak authoritatively on this, but, people are buying three percent hydrogen peroxide in those brown bottles from the grocery store and gargling with them, and putting them on wounds. Three percent is 30 thousand parts per million, is what that is. I think, even the highest thing I’ve heard tested was 1000 parts per million, and that didn’t seem to do damage to people. But again, don’t take my word for it. It, at least, seems anecdotally out there. It’s not like 100 is a danger zone when these bubbles are forming. I have not heard anything about that actually being a point where this would be harmful to your skin or even if you got it in your eyes, necessarily.

Graham: No real damage that we’ve been able to assess anywhere. As far as we can tell, this is actually the most negative byproduct you get, is, little bubbles and bleaching of the hair.

Ashkahn: Yeah, around that range. That’s why most people stop there. There’s not really … also, as far as I can tell, doesn’t seem like you get a huge benefit from having hydrogen peroxide levels much higher than that. Seems like their ability to oxidize and do the things that they’re doing peter off around 40, 50, 60 parts per million, something like that. You’re not getting a huge bang for your buck by dumping a ton of peroxide into the water.

Graham: Is there anything else that we think is likely to be causing bubbles in someone’s tank? I was trying to think of that while we were talking, and thinking and talking is hard. I decided to do one at a time.

Ashkahn: The bubbles, tiny bubbles, as you’re floating, or something like that, is almost always hydrogen peroxide. The other thing that can cause bubbles is a small leak in your filtration system, right? If you have a pinhole leak in your union. Then when you run your filtration system. Or if your water levels are too low, and your filtration system is sucking air in as you run it … But, that’s real obvious. You run your filtration system, all of a sudden, your whole float tank’s cloudy. It’s been chopped up like a blender, and it gets sent back in. That dissipates pretty quickly, too.

Graham: That’s a problem at the beginning of the float, but not something that would be ongoing. They even say, “small bubbles.”

Ashkahn: Visually, those are so different. Tiny bubbles that are persistent in the water during your float, versus, your whole float tank turns cloudy white for 10 minutes.

Graham: Alright. So, answered?

Ashkahn: I guess so.

Graham: Alright. And that’s our solution for today.

Ashkahn: We’ll talk to you tomorrow.

Graham: Thanks, everyone.

It happens every once in a while that a center you knew closes down and it can seem like a dark omen for the rest of the industry. The reality is that these are individual circumstances that are brought about not because of a major trend as much as just life events coming up. 

Graham and Ashkahn share their take on other float centers closing and what they know about it and how frequently they think it’s occurring.

How to Build a Green Float Center – DSP 292

Graham and Ashkahn talk about the options available for sustainable options when building a float center, or more accurately, the lack thereof. Unfortunately, the materials necessary to make a float room saltproof and waterproof tend to be very unfriendly for the environment.

It’s been three years since our last Giveaway, and we thought that it was long overdue for another one. So, what’s the dealio? The Giveaway is a chance to give a big ol’ boost to a deserving Float-Center-To-Be. This time around, we’re taking things to a whole new level, with over three times the value of products and services being given away. To you. For free.

Dear Everyone: Please reconsider building your own tanks

Dear Everyone: Please reconsider building your own tanks

Look, we get it. Really. Float tanks are expensive – especially for what can seem, from the outside, like a glorified bathtub with spa parts attached. It doesn’t take long to go from, “Why is this so expensive?” to “I’ll bet I could save money by making my own tank!” After you start mulling it over, you get excited. You could be offering something no one else does right now… because it’d be your own creation! How hard can it possibly be?

As experts in only thinking about half of the consequences of our actions (at best), we’d like to say, “Incredibly hard, actually!”
