Hard water is something that comes from having too many minerals in your water source. It can cause a lot of problems with plumbing if it’s too hard, and most buildings will have resources for dealing with this to help avoid calcium buildup in pipes and along tubs or pools. As for how it interacts with a float tank, specifically, it seems like the larger issue is going to be how it impacts the rest of your building.

Graham and Ashkahn break down what they know about how hard water affects float tanks and the differences you’re going to have to look out for if you’re using well water over municipal water sources.

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

Graham: And today’s question is – actually questions are “hard or soft water? City or well water? For one tank only please.”  Well fortunately, those aren’t really going to change for multiple tanks.

Ashkahn: Yeah, they should be the same.

Graham: That’s the good news, yeah.

Ashkahn: Okay.

Graham: So there’s a difference between them.

Ashkahn: Between hard and soft water?

Graham: Yeah.

Ashkahn: Yeah, should we explain what that is?

Graham: Yeah, I think we totally should.

Ashkahn: All right so hard and soft water’s usually referring to the amount of mineral content of your water. Hard water has a lot more minerals and metals and stuff like that in it and soft water doesn’t. Typically, I think there are some issues that come with having hard water. People usually want to have softer water. If you’re in a city with very hard water, you usually have a water softener. If you’re in a city with soft water, you don’t have a water hardener or something connected to your building or anything like that.

Graham: Yep. There are some things that come along with overly soft water, as well. But the interesting thing is this doesn’t really effect the float tanks themselves too much.

Ashkahn: Yeah.

Graham: It’s a lot of your other building appliances and things like that, especially if you’re filtering the water going into your float tanks which we fully recommend. If you don’t have a full point of entry building water filtration system, then at least filtering any drop of water that’s being added to your float tank when you’re topping it off or doing a full refill will often get rid of a lot of the minerals and different things you’re worried about building up and being deposited.

Ashkahn: So water hardness can affect pools and hot tubs and stuff like that. They’re often controlling their water hardness and measuring it every day because it can lead to scaling, that’s the term for … people are probably a little bit more used to seeing this in their showers in cities where they live with places with hard water, those buildups of calcium and lime and stuff like that that form that weird almost scummy looking surface thing that usually builds up on tiles or something. So pools and stuff, they can deal with that and it doesn’t look good aesthetically but also that scale can build up inside of pipes and that can constrict pipes and hurt your flow rates. It can also build up on the outside of things like your UV light, that sleeve glass tubes that the light bulbs are in can have scale building up on them. That means the UV light won’t be able to penetrate through that and it will hurt your UV ability. Or scale can build up on the heating elements of a heater and eventually damage those or make them less efficient.

Graham: Yeah, really common on hot water heaters. A lot of the time, the first times you’ll see an impact of having a really hard water going through anything in your system will be around the hot water heater and gathering on those elements or down on the little unions. The heat definitely because it can evaporate out water, gets the minerals just that much closer to coming out of the water and bonding to something else.

Ashkahn: But for some reason, we don’t see this happening in float tanks. Obviously, some reason to do with the Epsom salts but I don’t exactly know why. We tried looking into it and it gets to be some complicated chemistry out there.

Graham: We’re not scientists. We’re simple people.

Ashkahn: There seems to be some information about magnesium prohibiting calcium from really being able to form calcium deposits very easily.

Graham: Yeah like it’s crystalline structure gets disrupted by magnesium maybe if we’re reading these articles correctly.

Ashkahn: Here’s what I do know, I’ve never seen it happen in our float tanks. I haven’t seen it happen in anybody’s float tanks.

Graham: Or in our pipes or anywhere. It really does not seem like the hardness of the water, even if you’re not filtering the water going into your float tanks, has a big impact on the actual float system.

Ashkahn: So that part is pretty cool. It doesn’t seem like we have to worry about it that much, at least from what I know now and what’s been going on. Much more likely, you’re dealing with hard or soft water, probably just for normal things in your shop. Probably your showers are the biggest concern and your hot water heater that’s giving hot water to showers and your sinks and all the normal-

Graham: Bidets.

Ashkahn: -Non-float tank plumbing things that you’d have in your building are probably actually why you’d be trying to make sure you have a water softener if you have really hard water and dealing with that. Not a very float tank issue but still something you would have to deal with just because of the amount of other water fixtures that you have in your building.

Graham: For city versus well water, the advice just ends up being the same for both which is regardless, make sure you’re filtering it going into your float tank. Well water can end up with interesting minerals. City water is often has trace elements of chloramines for disinfection or bromides that they’re putting in there. You want to filter that stuff out but, again, you want to filter in either case. There’s nothing different that needs to happen as a result of having a different water source at all.

Ashkahn: Yeah. Probably not going to. As long as your well water is decent and there’s a lot of cities that can inspect wells and make sure everything looks good and how the well is set up. Only if you’re using a horrible well, it’s all weird and stuff, you might have problems but assuming that’s not the case, then you should be really fine both ways.

Graham: Yep. Watch out for, if you are in a well, that might mean you’re also on a septic system. That’s something to check in. Depending on the size of the system, especially the salt water, you can risk killing off the different bacteria that are making that system function. So I’d say that’s almost more of a concern than the water going into the tanks is what you’re doing with the water coming out on more of land use kind of level.

Ashkahn: Totally.

Graham: Cool.

Ashkahn: Yeah.

Graham: Well thanks for the couple of questions.

Ashkahn: Yep. And if you have more questions, you can go to floattanksolutions.com/podcast.

How Marketing Strategies Evolve – DSP 230

Graham and Ashkahn wax nostalgic in this episode tracing back the history of Float On to its origins. They were younger, bright eyed and the world felt full of possibility. How they advertised floating was a whole different beast back then, too. Part of it was how different the industry was, part of it was how different awareness in Portland was, and parts of it were just about Float On still being a young business.

The guys share their successes, lessons, and bold faced mistakes they made along the way in learning how to deal with the idea of filling tanks, as well as some of the constants that have remained throughout the years.

Future Proofing Float Tanks – DSP 229

Float Tanks are expensive. Purchasing tanks can easily end up being half of your opening costs when starting out, so it makes sense to want to purchase tanks that have a long lifespan. 

Thinking about which float tank manufacturers might last the longest, though, is probably not the way to think about this issue. For one, it’s impossible to tell what manufacturer is going to be around the longest. What’s more, if anything does break, the vast majority of the time you don’t need to go to the manufacturer to get it fixed in the first place. 

Ashkahn and Graham share their thoughts on proper float tank care and the steps any float center owner should take when considering a tank. 

How to Run Experiments with Floaters – DSP 228

It’s important to acknowledge that float center owners without a scientific background probably shouldn’t be running experiments on floaters willy nilly. It should also be noted that Graham and Ashkahn aren’t scientists, despite being huge fans of self-experimentation. 

There has been a lot of talk recently, however, of float centers collaborating with student researchers to help run experiments, though. Graham and Ashkahn discuss (with a fair amount of levity) what it might take to properly run experiments in a float tank, which they understand is no easy task. 

What are Good Plants to Have in a Float Center? – DSP 227

Plants give life, both aesthetically and literally, to any room they’re placed in. The environment inside a float center, however, can be the absolute worst place for certain plants, even ones that would normally be considered fine for your local area. 

Graham and Ashkahn pull in Jordan to talk about different plants that thrive in a humid float center environment and some tips on how to take care of them.

Getting Salty With Speakers: Roy Vore – DSP 226

With the Float Conference coming up, Graham and Ashkahn are talking with lots of really smart people who will be presenting this year. It’s not every day that they get to ask molecular biologists questions about float tank sanitation, so they decided to take the opportunity to ask the experts the questions that the industry needs answers to.

Today Roy Vore is taking time to share some of his knowledge about microbiology and water sanitation, along with his work in the pool and spa industry.

Choosing a Water Heater for Your Center

Choosing a Water Heater for Your Center

You may not be surprised to hear that a Float Center is a business which has a hefty water requirement. You may, however, be surprised to hear that the majority of the water demand you’ll be facing day-to-day is going to be in the form of showers and (if you’re doing any laundry on-site) a washing machine.

The factors of energy usage and cost over time should also be taken into consideration when deciding upon your water heater…

Float Fund – NSF Magnesium Sulfate Test Results

Float Fund – NSF Magnesium Sulfate Test Results

I’m happy to announce to first results from the Float Fund testing. This experiment, run through the NSF, was to see how salt water, with no other form of disinfection, actually effected harmful organisms. We ran tests with two different microorganisms, and in this post we’ll talk about how one (Pseudomonas) got its ass kicked by salt-water and how the other one (Enterococcus) didn’t seem phased in the slightest.

If you want to skip straight to the test results, you can download them in their entirety. Since they have a lot of fancy laboratory lingo, we’ll spend the rest of this post breaking down the different aspects of the testing.

Float Memberships and Packages

Float Memberships and Packages

Customers are great, but getting those customers to commit to returning on a regular basis is even better. There are a few different schools of thought in regards to encouraging return customers, but they’ll generally fall into two main categories, Memberships and Packages.

We’re going to provide a little insight into how to utilize each of them at your center.

Marketing is all About Relationships

Marketing is one of those words that has a lot of different meanings from one person to the next. Personally, I’ve studied marketing in one way or another for the past 20 years. I suppose you can say I’m a marketing nerd (I’ll wear that badge proudly). I even annually budget myself a different marketing conference to go to… for fun.
