I have gained a lot of valuable info from this site already. Three weeks ago, we purchased and put up a 5,000 gallon Intex Ultra Frame pool (16x48). We upgraded to the larger pump and also got a SWCG. Initially I went to the pool store with samples, but quickly found out that they know very little and just want to sell me more chemicals. By reading on this site, I think I have been able to figure out the pool and get it into "proper" swimming levels.

I run my SWCG 4-6 hours per night (initially I had low chlorine) and my filter 8 hours. The pool is very clear. The bottom does get some algae like substance in a few places, but it is easily brushed off with our feet when we swim. I have taken charge of monitoring for the last week and a half and have kept the following #s consistently.

Chlorine- between 3-5 depending on time of day
ph - 7.3
Alkalinity - 180/190
CYA 20 (this was tested the day after I added the acid - I thought I remember reading that it can continues to rise a little)

My alkalinity is high, but I'm thinking that is okay since my ph is stable? I just want to make sure my kids have a safe place to swim. Thanks!!
