I’m hoping that some of you on here can either give me advice, or put my mind at ease.
At the start of August, I inherited a ten year old Hydropool hot tub. It was in reasonably good condition. It had been serviced by a local pool company throughout its life. That being said, they rarely had water tests done. They ran with a non chlorine based shock, bromine tablets and stain and scale control. All BioGuard products. When I picked up the tub, it had been sitting with water for about a week and not circulating. Then it was drained and empty for a week.
When I got it set up, I shocked with brominating Concentrate (quadruple shock) and ran Swirl Away. Upon refilling I noticed white flakes throughout the tub. I purchased AhhSome and a new filter. Ran the AhhSome and shocked and got a lot of brown stuff and a ton of foam. Drained. Rinsed and filled. Still had white flakes. Ran another dose of AhhSome. Got a lot less, but still some brown. Drained. Rinsed. Filled.
I ran a chemical called SpaPurge from SpaSolution that required me to have the pumps on for eight hours for five days. Didn’t really do much in terms of adding anything to the water. Shocked and drained.
I super chlorinated to 50+ ppm and let circulate for an hour, or slightly more. Drained.
Refilled and shocked and ran AhhSome again. Very little brown this time. Drained. Rinsed. Refilled.
Shocked to 50+ ppm (four full caps of Brominating Concentrate) on advice of pool store. Let pumps run on and off for 24 hours. Drained. It bleached the heck out of the filter. Rinsed and refilled.
Shocked to 22ppm with 6% Clorox. Covered and let sit for 24 hours. FC dropped to 18.5 in 24 hours. Pump had still been running for the four hour circulating during this time but nothing else was adjusted or changed. These FC levels were tested by my pool store with a Taylor kit.
Added half cap brominating Concentrate once the FC level dropped. Let run for a week with about five hours total use by two people. Had a floater set to 3. Bromine level has remained over 6 ppm all week.
I ran AhhSome again today and got an almost negligible amount of brown in one spot. Wiped with a paper towel and barely noticed it on the paper towel. Got white foam though.
I put my hose on the jets where I think more of the flakes come from. I was able to release a few quarter inch pieces. Put some in a mason jar with Clorox. Nothing happened. Put some others in a mason jar and brought them to the pool store. They poured Muriatic Acid over them. Nothing happened (noise, fizzing, etc). They maybe became slightly more transparent but definitely didn’t disintegrate.
The flakes mostly seem to come when I run the second pump (there are two plus a blower).
Im stuck. I have no idea what to do now. The tub is usable, but is this safe? Can I let my kids in, or should I keep them out?
I was under the impression it was biofilm and WWM but I’m assuming because of the AhhSome purges, being able to maintain a sanitizer level, and the flakes not disappearing in the mason jar, that this would not be organic. So I figured calcium. My tub seems to be too old for Calcium stearate that some talk about. I thought maybe calcium flakes, but then figured it’s probably not that based on the Muriatic Acid.
Sorry for for the length of the post, but I’m hoping that someone has some suggestions for me! It’s a beautiful tub and I would love to have the piece of mind of letting my children in!
I have attached a link to a video that I took this evening showing the water after the pumps had been running: http://www.youtube.com/watch?v=O9MaUPlyqWs
