Just wanted to stop in and say hi!! I have been lurking around for awhile and just decided to join. I have been a pool owner for ~20 yrs (but I am in no way an expert or even close ). My current pool is a 20x40 inground cement bottom with fiberglass panels which I am currently in the process of getting repainted and recaulked. I run a Hayward sand filter with auto-chlorinator. Tried running auto-vac but have had limited success with that. I have had varying degress of success maintaining my water, some years was fine others a season full of pea-green soup . I have even tried the BBB method one year but I obviously did not do it properly (after learning more about it here). I also realize that I need a real test kit. I am looking forward to learning as much as I can here and hopefully not spending mass quantities of money on pool maintenance this year........ Any way hello and thx..
