    Chlorine level ok for swimming?

    Hey everyone - My FC is at 8.0 and CYA is 40-50. Pool math app puts that at the top of the recommended range. Is this ok for swimming? My kids are getting anxious :) My FC comes down very slowly after opening and shocking cuz I have the solar cover on all the time. I have turned the SWG off...

    TA at 90 - too high?

    Hi everyone, I recently added CYA to get my level up to 60 (it was 0.... pool was built and filled last fall but not used till now). pH was 7.8 before starting the addition now it's 7.2, which makes sense. However my TA went up from 80 to 90 (the drop test is subjective though because it...

    Adding CYA to SWG pool

    Hi all, End of last year I got an inground pool with a SWG installed. Previously I had an above ground pool so I'm familiar with the care, but I'm unsure of how much CYA I need for an SWG pool. Right now I have the SWG at 50% and my FC goes between 2.5 and 3.0. I have no CYA in the pool...

    Intex Pool - support posts leaning

    Hi all, I have a 22 foot diameter intex pool. It was installed by the previous owners of my house. We moved in here in the fall of 2018. I noticed recently (within the last month) that a few of the post are not straight. See attached pic. A rough measure has them about 5 degrees off plumb...

    What size cover to get?

    I have a 22' round pool that was installed by the previous owners of my house. The cover they left was a piece of junk, so I got rid of it. The only sizes I'm finding are 21' and 24'. I meant to buy a 24' on amazon but accidentally got the 21'. The measurements indicate it's 25' in diameter...

    Cleaning up mess previous owners left me

    Hi everyone, new guy here. I bought a house last October, and the previous owners had covered the pool. I don't think the water was in very good shape before getting covered. Cover way way too big for the pool, and was constantly blowing off over the winter. I didn't have much time to deal...
