Hi, I feel like my CYA is getting a bit low at 30 (it's been gradually going down over the last few months; I use liquid chlorine only and muriatic acid to control ph.) So I bought some stabilizer. I'm just wondering how much to add to go from 30 to 40 in a 20,000 gallon pebbletec pool? I don't...

So I use the Taylor K2006C, and I usually do the 10 ml. sample. The instructions state "add 2 dippers R-0870". The actual dipper itself seems kinda arbitrary to get the correct amount. How much would too much or too little of DPD powder affect the test?

CYA: 50 FC: 6 CC: 0 CH: 450 PH: 7.6 TA: 80 21,000 gal pebbletec pool. Arizona. Pool water currently about 88° during the day. A week or so ago my TA was 110, and my PH was 7.6, sometimes 7.7. I guess PH of 7.6 is "ok", but I was trying to get it to 7.5 or 7.4 - just to see if I could. So I...

Since I replaced my pool water a few weeks ago and finally bought a Taylor K2006A test kit, I've been testing every day. I don't always to CH or CYA, but I always do FC, CC, PH, TA. Is that excessive or normal? Wondering what others do....

I believe I've seen it said here that FC should be 7.5% of CYA. In other words, if your CYA is 50 then FC should be 3.75 (let's say 4). I've also been referred to the Chlorine/CYA Chart which says that for a CYA of 50, FC should be 6 to 8, with a minimum of 4. So is the 7.5% calculation that...

Maybe in different parts of the pool? Or how long should you wait? Also, one thing I read about adding muriatic acide said to do it when the filter pump has been off for an hour, and dump it in the deepest part, and wait another hour before turning the pump on. Is that correct? [Link Removed...

So I got a Taylor K-2006C test kit. Tried the chlorine tests today for the first time, carefully following instructions. I used the 1 drop = 0.5 ppm and the 10 ml sample. My question is: how long are you supposed to wiat, or take into account time, when getting the water to turn colorless? In...

Hi. New here, having some trouble with my chemistry (low PH, high TA). I have a 21,000 gallon pebbletec pool. I heat it, min temp is 83 but its now going over that in the daytime as it heats up here in Arizona. So temp is about 85 or 86 now during the day. My stats are this at the moment...
