I've been reading through some of the forum topics and have a few other questions that I couldn't answer.
On my drop test my readings are
Combined Cl test .6
I'll have to look up the other readings I had but I know the stabilizer was okay and alkalinity was high.
I just moved in a month ago, the pool has always been sparkling clear even though the cl readings have always been too low. Ph has always been too high. I read that you need to adjust pH first because it makes the cl more effective (I use the pool Cl from home depot). The pool had a ph of 8.2 when I first started. I backwashed and added DE. I've been slowly adding acid (about a half gallon a day when the filters are running) and got it to 7.6 for a few days, I added Cl after that.
My CL went up to normal levels after that, but decreased a few days later. At the same time pH again began to rise and I kept adding muriatic acid (also from home depot) but the last week I've added probably 2 gallons and the pH always goes back to about 7.8 after a day. My spa waterfalls into the pool, I read on your forums that can cause the pH to rise but I can't control that part of my pool. It almost seems like there is something else going on that is killing my muriatic acid dosages and also with the high levels of stabilizer present I wouldn't think my Cl levels would go down so quickly.
I read here that normally you slam the pool when the pool is green or has an organic problem, my pool does not seem to follow those problems and even without the normal Cl readings the pool rarely has any algae growth. Because the chemicals seem to not be helping much, should I slam it with liquid chlorine anyways? I just don't want to keep buying chemicals if I need to slam it first.
The pool does have a SWG but it is no longer functioning, there is still salt in the pool and I am planning on getting a new SWG soon but don't want to empty the entire pool right now as it is at 30 gallons of water.
