My pool--quartz composite similar to ultrapoz-- is only 3 months old and already has CH of 750--according to the Expert the pool builder sent out. Leslie's had my last reading at 430. Because the pool is new, and the 400+ CH reading, I was already trying (acid almost every day) to keep my ph down to 7.3/7.4 (tends to drift up .1 - .2 overnight) and TA at 80-90 (cya is 80). But the Expert said the TA was too low because of the high cya, and I should keep it at 100-110. But the CYA goes up and down, depending on backwashing, what stage the tab in the floater is in. And how can a new pool have a CH of 750 already? They told me it was normal, but I was told I'd never have to drain my pool because I have a sand filter--large Pentair. Pool is about 13500, UV system, bioguard silk for back up sanitation, no salt, Barracuda G3 for cleaning. We only backwash every two weeks, and even then the pressure gauge hasn't gone up. We just do it to refresh the water in the pool. Now I've been told to drain the pool in Feb. or March because the CH can't go higher than 1000. Leslie's had my TDS at 2300 or so, with 1400 salt and CH of 430. The expert has me at 1800 TDS, salt at 1400. Do those numbers even work with a 750 CH?? (FYI: Per expert testing, Tap CH is 170; TDS 800; TA 110)
Any advice? Is this pool draining bull? The water is crystal clear, feels great, equipment function well without any build-up that I can see. There's strong flow from the returns, even on the lower speed. Since the first few weeks we had the pool filled, there has been a white calcium build-up at the water line and on the tile grout that we've had to scrub off, but we haven't even had any white line at the water line for over a month. I don't want to screw up the warranty --or my interior-- but it doesn't seem normal that I'd have to drain a brand new pool. Maybe with old pools and pools with cartridge filters, but a new pool with a sand filter. Something is just not right.
I have also had problems with testing from local pool stores. Have learned that neither Leslie's or B&L test their reagents against a standard. They don't seem to follow the kit instructions either. They do so many all day long, I think they're sloppy. So, chances are none of us is getting a good reading. They really should go to a computerized system. Calibrating the computer a few times a day would take less time than their inaccurate test kit testing. I bought a commercial kit and had it tested against standards because I was tired of dealing with the different readings from different places. How can you balance your pool if the numbers are wrong? Not even sure I trust my own testing. Does anyone know of a place in the Phoenix area you can take your pool water for a professional computer test--even if they charge for it?
Thanks for any advice you can give me. I'm at the end of my rope.
