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.

When setting up your float tank, it can be tempting to look at the spa pack and imagine how much more convenient it would be if the pieces were rearranged a little bit. So… is there a particular order to the filtration equipment? Why or why not? 

Fortunately, Graham and Ashkahn have painfully researched this issue and know all the ins and outs of water treatment systems for float tanks and why they are the way they are.

Pairing Psychotherapy and Floats – DSP 154

It’s easy to look at some of the research that comes from floating or look at special programs for veterans with PTSD and think about how float tanks should be paired with psychotherapy.

Graham and Ashkahn have met several therapists who use float tanks in conjunction with their sessions, sometimes exclusively. They also know that it’s important to recognize that they are trained professionals who are providing a treatment for difficult to treat psychological issues in some cases. Knowing when to leave the work to the experts is a valuable part of providing a service like this one with so many broad uses.

What is too small for a 4-tank float center? – DSP 153

Real estate costs from building out a float center, especially in an urban area, can get costly really quick. Sometimes compromises need to be made. But how much of a compromise is too compromised?

As with the best float center mistakes, Graham and Ashkahn can speak to their personal experience on this issue. They talk about opening a four tank center with less than 1,000 square feet and how much of a mistake it is. They also provide helpful planning tips so you can find out how much space you need at an absolute minimum for your float center.

How Do You Find Time for Hobbies? (Rise) – DSP 152

This is the last episode we recorded at Rise and it seemed fitting to close out the recordings with the organizers again, Jake and Kevin. In this episode they talk with Graham and Ashkahn to answer a question from Greg Griffin about how to manage your time after opening a float center to dedicate to hobbies. 

While the episode starts a little heavy, the conversation turns and begins discussing the value of work and how rewarding it is to be in this industry. 

Thank you to everyone who came and talked to us at Rise and shared your experiences. If we don’t see you at the Float Conference, hopefully we’ll see you next year. As always, float on.

What’s the Weirdest Post Float Experience You’ve Seen (Rise) – DSP 151

Another conversation that was captured at Rise was this little sit down between Graham and Ashkahn and a float center owner by the name of Jeremy out in San Antonio. They talk about a subject that I think comes up whenever float people get together. “What’s the weirdest thing you’ve seen after someone got out of a float?”

Sometimes people have a hard time coming back to Earth after a really good session in the tank and seeing how they interact with the rest of the world afterwards can be heartwarming and enlightening. It’s part of the reason we do what we do.
