Obviously float centers need a lot of salt. The average float tank requires roughly a thousand pounds of salt to maintain a specific gravity high enough to be functional. What about after you get your tanks filled and ready to go, how much do you need to have on hand just for maintaining that level? Fortunately, Graham and Ashkahn have a good rule of thumb for how they run Float On to use as a metric, as well as some good simple tips to keep in mind about storage in your float centers.

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

Graham: So, today’s question is, “How much salt should you have on hand at any given time?

Ashkahn: How much salt? I mean I got my general rule.

Graham: Was is going to be a lot? That’s what I was going to say.

Ashkahn: You don’t want to have a little bit of salt, that’s a big problem.

Graham: Trust us, this isn’t the line of work for that.

Ashkahn: I like always having at least one float tanks worth of salt on hand. You’re biggest float tank if you have different models. I never want to not be able to refill a single tank at any moment. That way you’re just prepared. Whatever happens you can totally drain and fill a tank. If you don’t all of a sudden, who knows you might have to shut that tank down for a few days. That’s a lot of lost revenue. That’s kind of my comfort zone. If we’re ever less than a full float tanks worth that we have in storage or in our lobby or whatever that’s the danger zone to me.

Graham: So really that’s when you have your biggest float tanks worth of salt, the order should be arriving on your doorstep that day to replenish your salt.

Ashkahn: Right. Littlest amount.

Graham: That’s your lowest amount that you possibly want. It’s just because something could go wrong. If your batch of salt gets contaminated by something in a float tank then you want to be able to immediately, day of, start that refilling process.

Ashkahn: Right.

Graham: Because that makes sense. Then you know other than that it’s I guess moving up from there, how much salt you keep on hand and how much you want to be reordering it.

Ashkahn: Right. I mean every company I know of, the price gets cheaper the more salt you order at once.

Graham: That’d be weird if it was …

Ashkahn: More expensive. “You want how much salt?”

Graham: “No, that’s really going to cost you this time.”

Ashkahn: It’s tempting. I mean when we order salt I’m constantly in my head, “I should just order 50,000 pounds and then we’ll get a warehouse and we’ll store it.” When we’ve crunched the numbers, it’s really hard to make the finances actually work out. If you’re paying for storage, if you’re paying for storage that’s just there to house salt so that you can order a bigger order to bring the price down it almost never actually saves you more money than the cost of the storage space.

Graham: Almost no matter what it is even if we’re talking about 75, 100 dollars a month or something to store that salt, it immediately eats into that profit margin.

Ashkahn: It just doesn’t seem to work out. Here’s the best idea we’ve had. Feel free to steal this one. The best idea we had to solve this problem was just to replace all the furniture in our house with salt bags. Just make a couch out of salt bags and a salt bag TV stand. The problem was that we realized we’d slowly start losing our furniture over the course of us using the salt.

Graham: I also do think that same idea is applicable in float tank a lobby as well. Just have your whole lobby furniture made out of salt.

Ashkahn: Just constructed out of salt bags. So, that was pretty tempting but we never …

Graham: I thought you were just going to say invent anti-gravity and this whole salt thing really solves the problem.

Ashkahn: That’s the real solution.

Graham: So that said, how much salt do we order at a time when we order salt?

Ashkahn: Well, so we keep salt in our lobby.

Graham: The furniture thing again.

Ashkahn: Furniture. Kind of, yeah. Then we also have a storage shed out near our office. Which just kind of comes with our office, we’re not paying any extra rent for it so it’s not part of the math equation of salt cost. Basically we order as much as we can to fill those spaces. For us ends up being about 10,000 pounds of salt. That fills up our shed and then there’s a nice little stack in our lobby.

Graham: I think the biggest order we did was for around 15,000.

Ashkahn: Yeah, once.

Graham: That was just … Once again, it spill over into this area where we had to pay for a little bit of storage. It kind of made it not worth storing any more.

Ashkahn: We were filling tanks up right around then. That’s mostly what we do. We’re often ordering it. At least that lasts us about six months. We’ll order that.

Graham: Once a year we’ll be doing our tank refills, it’s the regularity that we’re doing that. Just to give you guys an idea.

Ashkahn: We’ll do a tank refill and we’ll order salt right before that because we use a lot of salt in that process.

Graham: And, we have six float tanks. We’re opened 24 hours a day. We run around 1,300 floats a month. We run a lot of floats that are using up that salt as well. When you do the averages it ends up being about 1.1 pounds of salt per person, is what we end up losing per float.

Ashkahn: But, I mean really going to the question of how much do you have on hand; if we didn’t have that storage unit, we wouldn’t be ordering that much salt.

Graham: Very true. On the other hand, some of the other centers that we’ve visited, if you just have a ton of back storage or you have all this space that you can use that you’re not making use of, then order even more. Again, it only gets cheaper the more you have. It’s not like your Epsom salt is going to hit its expiration date.

Ashkahn: It’s not going to go bad.

Graham: Yeah.

Ashkahn: You can make some nice furniture out of it.

Graham: All right. So, there you have it. As much as you can and never less than enough to fill your largest float tank.

Ashkahn: Okay.

Graham: So, thanks for tuning in. As always, if you want another question like this or even easier than this answered, feel free to go to floattanksolutions.com/podcast and send it in there.

How to Deal with Humidity in Float Rooms – DSP 185

Humidity can be a subtle, difficult, and persistent challenge for a lot of float centers. Aside from just the massive amount of humidity that a float tank can create, showers also generate a lot of humidity. This can be a challenge for your construction, your soundproofing, and your floater’s comfort. 

Fortunately, everyone has to deal with this issue, so there’s a lot of tips out there. Unfortunately, there isn’t an exact science on the best humidity for float rooms as of yet. Graham and Ashkahn unmuddle this quandary a bit before muddling it back up again. 

What to do if your Float Center Loses Power – DSP 184

What do you do with your float center if an emergency happens? What if your center loses power for several days and there’s nothing you can do about it? Float tanks rely on having a well regulated system to stay functional and we know that if it gets out of whack, everything can get pretty messy. So if you know this is happening, how do you prevent the worst of it? 

Graham and Ashkahn work through this problem and come up with some solutions to prevent things like salt crystallization and upsetting your tank chemistry too much. 

How to Handle Business Partner Disputes – DSP 183

It’s often said that having business partners is a lot like having a marriage, and just like a successful marriage, having a successful relationship with your business partner (or partners, we’re not here to judge) requires effective communication, patience, and compromise.

Float On has 5 owners, and they haven’t always agreed on the best course of action. So naturally disagreements happen, but how you handle them is the worthier part. Graham and Ashkahn share their experiences and what’s helped make Float On a success 7 years and counting. 

Float Center Name Suggestions – DSP 182

Fortunately, Graham and Ashkahn have taken the time come up with a list of a few floaty sounding names that are so far not taken but totally awesome. 

What Benefits of Floating have been Proven Scientifically? – DSP 181

Most float centers have to deal with the difficult problem of describing the benefits of floating to those who haven’t tried it yet or are just starting their float journeys. What is safe and accurate to say? Obviously, you don’t want to be advertising false claims if you can help it, but it can be difficult to find accurate information that tells a full story about floating.

Graham and Ashkahn dive into the resources available and clear up some of the confusion surrounding our salty practice. Check out the show notes for a list of great resources!
