We use our SPA every other day and we use Chlorine and keep a close eye on the water health. Noticing our test strips were testing high for Cyanuric acid (CYA) and the PH kept going very acidic (dark brown off the scale, this is a good sign of CYA overdose), we constantly had to add alkaline everyday but only really reducing the alkaline small amounts. The chlorine remained high even with not adding it for a several days as though the CYA was keeping hold of it in the water. We discovered the stabiliser part of most of the chlorine tablets/ powders is CYA and the tub was overdosed with it causing all readings to go out. I beleive this is fine in conditions where your hot tub cover is mostly off in sunny areas as this burns off, but in our case where we have to put the cover on after use as it's cold in England generally we found this issue. We replaced half the water and switched our chlorine tablets with a liquid that contains no CYA (this is hard to find, and you MUST read the ingrediants as there's products out there that claim its free of CYA but when reading the ingrediants it not). After using the liquid the levels went back immediately and have been perfect ever since.. we’ve been able to put less chlorine in and hardly adjusted the Ph, and it stays balanced with less foam. we believe that the CYA will burn off if its exposed to UV over time but this case as we have to put the cover on regulaly so there's no way for it to escape or lower. I hope this helps some people. -
I have a cyanuric acid level of 165 (perhaps a bit higher now) and have received conflicting information about how much water I need to drain from pool. The manager of my pa ool store insists I have to drain completely. Others say 2/3rd drain should be enough. One source suggested draining my pool (which varies from 3 feet to about 5 1/2 feet in depth and is about 12000 gallons) to around a foot and a half. Does anyone have any thoughts on this? Thanks

Hey Guys I just got a new pool put in my yard. 38K gallons salt water. Has ozonator. I've gotten 3 water tests in the last 3 weeks and the first one told me to add 18 pounds of bioguard stabilizer 100 (cyanuric acid). Literally spent HOURS pushing it around my pool until it dissolved. Then most recent test a little over 2 weeks later said my cyanuric acid levels were back down to 0 and that I needed to add another 18 pounds. Is that even possible? If the sun is out, it is on my pool all day. Never gets any shade. But I've read and seen in so many places that you only need to treat your pool with cyanuric acid once per season. Why have I had to put 36 pounds of it into my pool in less than 3 weeks? If anyone has any suggestions or ideas, I would greatly appreciate the feedback. Also if there is another way I can maintain the cyanuric acid levels without having to spend 10+ hours doing so, would welcome those suggestions too. Thanks, Jason
