One of the biggest Float Mysteries in the industry is how to properly deal with condensation in a float tank. Your float tank is basically a giant humidity generating machine so clearly there’s going to be some condensation, but how much and why it forms can vary for seemingly no reason, making managing it difficult. The last thing any float center owner wants is for it to affect the floats they’re running (little water droplets falling on floaters is no fun).

Graham and Ashkahn commiserate with the industry about the difficulties in dealing with this particular hot topic, while also delving into the science of it and common solutions that should help any float center owner that’s facing this problem.

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

Graham: Today’s question is, “I have a bunch of water drops that keep forming on the top of my float tank. What should I do to stop that?

Ashkahn: Bummer.

Graham: So, first of all, this is really common. These things are giant humidity generating machines. So, it’s not the most surprising thing in the world that it’s forming on the ceiling there.

Ashkahn: Yeah. It happens.

Graham: The problem with this too, we should say, is not that it’s on the ceiling, it’s that mid-float you’ll get these water droplets that come down. It’s like this weird water torture where you don’t know how often or what body part it will hit.

Ashkahn: It’s pitch black.

Graham: Once every 20 minutes come down and disrupt your float.

Ashkahn: It’s pretty horrible. Once it happens, you just can’t relax anymore.

Graham: Yup.

Ashkahn: So, what causes it? What causes this condensation? What’s the condensation cause?

Graham: It’s giant humidity…? It’s a pool of water that’s kept at 94 and a half degrees.

Ashkahn: Here’s what I’m getting at: usually the condensation is either existent or especially pronounced when there’s a big temperature difference between the inside of the float tank and the outside of the float tank.

Graham: Like a soda can.

Ashkahn: Like a soda can, or like anything that holds condensation.

Graham: Like any object in the world.

Ashkahn: Various float tanks have things to try to prevent those too. From the way the ceilings are sloped to radiant heaters inside the ceilings like the Samadhi tanks have. I think some other float tanks might have that too. A lot of float tanks if they don’t have that will put a lot of insulation up at the top, things like that to all cut down on the problem. Still, if you do have a pretty serious temperature difference between the outside and the inside, which usually means colder on the outside, warmer on the inside. You’re going to get that condensation. I mean it always means that, otherwise the condensation would be on the reverse.

Graham: On the other side.

Ashkahn: When you have this situation that’s when it comes. There’s I think two big things to help deal with it. One, is humidity control. That’s part of it, is making sure that you’re trying to keep the area not extremely humid.

Graham: Even a little bit of airflow getting into the tank, hopefully not enough to disrupt the float or even be felt by the person on the inside, but just any kind of circulating air towards the top will also work to eliminate some of that condensation, which is nice.

Ashkahn: Probably the biggest thing that’s going help is keeping the room that your float tank is in warmer. Actually whatever heating system you have to heat the room, you might want to consider bumping it up a little bit and trying to equal out that temperature.

Graham: It also sometimes depends on time of year.

Ashkahn: Yeah, that’s what we find at our place.

Graham: Again with the temperature differential, winter tends to be the worse time for condensation gathering on the float tanks and causing issues. Even with kind of getting this ideal – at least with floater comfort, plus stopping condensation – interior air temperature down. We still have issues with that forming in some of our rooms and the solution we have right now is actually just checking the ceiling between every person and having basically a …

Ashkahn: Stick with a …

Graham: Rag on it. We just clean our tanks with a rag on a stick.

Ashkahn: One of those almost like a Swiffer-shaped thing.

Graham: We do that. We use a telescoping pole and go in there and get the humidity off the ceilings of the cabins just in between people. I was just talking to one of our staff yesterday and they were saying they found they have to do that in between every single float right now for one of our rooms.

Ashkahn: There’s definitely a certain mystery to it too.

Graham: Even when we have identical tanks and one room has a bunch of water forming and one doesn’t.

Ashkahn: They’re the same temperature. Sometimes I’m just like, okay there’s something going on here.

Graham: We call those … in the business we call those “float mysteries”. Get used to them – is my best advice for those.

Ashkahn: This whole conversation has sounded very logical up to this point, but in reality sometimes you’re still scratching your head. Wiping it off, I haven’t found it to be, even at worst case scenario if you’re wiping it between every float. It usually seems to do the job for the course of that float.

Graham: I love having it so the drops aren’t falling on people.

Ashkahn: Which is nice.

Graham: A couple other things to keep in mind. One is this idea of using like bubble wrap type cover for your float tanks. Oftentimes we’ll find the most condensation seems to gather when people aren’t using the float tank. Especially if you’re leaving the door closed to keep in the temperature. You want to keep the water temperature warm so you close the door to the float tank, you didn’t have a floater in there in that session, next person goes in and opens it up and it’s just drip city.

Ashkahn: Yeah, why? Why?

Graham: Because you’ve creating this contained environment. Something about humans and …

Ashkahn: Where’s the person in there? Why would the person change?

Graham: Float mystery. Don’t even try to worry about it, my friend.

Ashkahn: It matches with experience, but I don’t understand.

Graham: One thing is to leave the door to the tank opened so that doesn’t happen. You get the airflow going in, but then the water in the tank will get cool, which is where you have this combo of door opened perhaps, some kind of a bubble wrapped cover in the tank to stop heat from going up.

Ashkahn: It’s kind of like a light pool cover, I guess. We call it bubble wrap because it has a lot of bubbles on it. We’re not just like saving the bubble wrap scraps from our packaging.

Graham: Right, don’t actually just throw bubble wrap in there. Much more official than that. I promise you.

Ashkahn: They’re usually blue, kind of thick plastic. I mean you’re looking up a pool cover.

Graham: Very serious. It’s very commercial, professional.

Ashkahn: Professional business.

Graham: So, anyway, that’s one of the tricks at least when you have an empty tank in between some clients. Both keeping the water warm and stopping that massive amount of humidity from gathering on the ceiling.

Ashkahn: Yeah, you know it’s just rag-stick.

Graham: You can on some tanks, depending on the construction of the fiberglass, you could also retrofit it with a heater on the ceiling, if it didn’t come with a radiant heater.

Ashkahn: Yeah, that’s true.

Graham: Not possible on all tanks. You know, if it’s double shelled fiberglass, it’s going to be really hard to do any kind of retrofitting or anything like that. In a lot of the units it is actually possible to go back and put a radiant heater on top of the float tank – which like Ashkahn mentioned before – is how Samadhi and a few other tanks control the drips on the inside there, is actually having a heater that’ll heat the ceiling enough that it just kind of evaporates that water or stops it forming, which kind of is like the most surefire way to stop this from forming. Other than stick-rag, which obviously is without saying the best solution.

Ashkahn: Or, more insulation is a nice easy step. See if that works.

Graham: So, good luck. Good luck with the drops out there on your ceiling. Again even if you have to wipe it in between every person, the most important thing is just even if there’s humidity forming try to make sure it’s not falling on your customers. That’s where it starts to cause trouble.

Ashkahn: Okay. If you guys have more questions for us go over to floattanksolutions.com/podcast and just type them right into there.

Graham: Yup, those will go straight into our trash folder and we’ll make up our own questions from there. All right talk to you all tomorrow.

Are Tankless Water Heaters the Best? – DSP 270

Graham and Jake take on talking about Tankless or “On Demand” water heaters today. They break down a lot of the benefits of them compared to storage water heaters like the fact that they provide a nearly limitless source of hot water, require less energy consumption, etc. They’re not perfect though, and any float center considering one should look closely on how best to implement them. Jake shares some of the pitfalls of them as well as how to maximize their usefulness.

Should Float Centers use Light or Heavy Gauge Studs? – DSP 269

Still no Ashkahn today. He’s taking a couple of post-conference days to himself.

Jake and Graham are on the scene though to answer construction questions, though. Even the straight forward ones, like today. Jake informs us which to choose when doing construction, light or heavy gauge studs when constructing a float center, while getting a little sidetracked when comparing wooden and metal studs. 

Construction to Make Your Life Easier – DSP 268

Graham and Jake cover a wide range of construction tips to make running a float center easier. Everything from making sure you have extra storage to installing mop closets with sinks in them for dealing with heavy duty chemicals.

The advice is pretty much a shotgun approach of tips, tricks, and hard lessons learned throughout the years. 

Draining Float Tanks into Septic Systems – DSP 267

Graham and Jake tackle the difficulties of draining float tanks and how that process can differ based on different municipalities, different water treatment systems, or whether you’re using a septic system or not. 

Water treatment typically involves whole contained ecosystems and highly concentrated epsom salt water can impact that pretty drastically. The guys provide good tips for each type of system and what to be prepared for if you’re operating in a rural area with a septic system. 

The Difference Between STC and Decibels – DSP 266

Post-Conference Ashkahn is still out of the recording studio, but fortunately Jake is keeping Graham company in there. 

Graham and Jake break down the differences between decibels and STC ratings, two very important to understand when figuring out soundproofing. There’s a lot to digest in this episode, but fortunately the guys keep it easy to understand by providing a broad level overview of the different concepts.

Home sweet home! After so many months on the road, it was strange being back here in Portland. We were exhausted, excited, and a little travel weary. The first night back, I slept in my own bed for the first time in three months and the world just melted away.

Having travelled across the United States, I’m reminded of how insular Portland is. We are aggressively fixated on keeping things local. Local beer, ketchup, bikes, pet food, pillows, phone cases… it’s part of our charm. We want to reward people for living here and being a part of the community. It’s so pervasive that, after living here for so long, I kind of forgot that Secret Aardvark hot-sauce isn’t available everywhere, and that most cities don’t even recycle, let alone compost.

Our northern neighbor – a sister city, of sorts – Seattle is the largest metropolitan area in the Pacific Northwest. It’s the land of Microsoft and Kurt Cobain, and the culture here embraces both simultaneously. It’s tech business professional in the front and rock n’ roll grunge in the back. This blend creates a perfect storm of high energy business life and high energy nightlife, making relaxation a valuable commodity. Floating helps fill the void left by nightmarish traffic and overcrowded restaurants.

Given that it’s so close to home, the float centers in Seattle are a lot more familiar to us. Our visits here were more like a high school reunion than they were like the first day of school. During some of our visits, we were picking up conversations right where we left them.

Vancouver is the largest metropolitan area in Canada, and third largest on the West Coast. It’s a major hub for international trade, with one of the largest ports in the world, giving it a large migrant population, mainly from Asia, the Middle East, and Australia. It’s also been a long-time home to the Canadian film industry, and has even been nicknamed “North Hollywood.” Dozens of film and television productions from major studios film here every year.

Vancouver is very much an international city. It has large boroughs dedicated to varying cultures, including one of the largest Chinatowns in the world. The society here is more receptive to new ideas, always looking for the next big thing; it’s not surprising that floating has blown up in Vancouver as much as it has.

In the last 3 years, 10 float centers have opened up, most of them being larger 4–6 tank centers. The really interesting thing is how they all opened within the same short amount of time about 1 ½ to 2 years ago, within months of each other.

We finally made it back to the West Coast! We went through the Canadian Rockies and were overwhelmed by the beauty of it all. We drove through hours and hours of winding mountain roads, fertile valleys, and tiny towns so picturesque they looked like movie sets. It was so captivating, in fact, I suspect Graham and Ashkahn may have secretly replaced themselves with robotic doppelgängers to hike throughout Banff.

This post will focus on the smaller communities in B.C. that are bringing floating to new people every day. We also get to visit Canadian manufacturer Pro Float. They’re relatively new to the scene, just opening up earlier this year – another exciting sign of the growth in the industry.
