I just moved into a house in Phoenix Arizona with a 13,000 gallon in-ground pebbletech pool and I'm learning how to take care of it, been reading a lot of info here on the site. I'm pretty sure I need to drain and refill but can't do it until the weather cools down. I'm wondering if there is anything I should adjust in the mean time. I've been using The Pool Calculator to determine goals, and have been trying to keep my FC high because of the high CYA. The CYA result was obtained by diluting the pool water with distilled water 4:1 and then multiplying, not sure how accurate that is. I have the K-2006 kit, and current levels are:
CC: < 0.5
Calcium Hardness: 750
Water temp: 93 F
Also, with the levels being so high on some of these tests, will it affect the accuracy of the other tests? For example, I read that high chlorine will affect the accuracy of the Ph test but I don't know how to compensate for it. I've never seen the Ph test result above 7.4, and it will keep going lower each day unless I keep the aerator on. I've been trying to keep it around 7.2.
