Im here in Charlotte NC and just opened this past weekend...pulled the cover off and was happy to see some bright blue clear water with only a little green crud on the entrance to the intake (which has since gone away)
As this is my 3rd year of TFP and BBB, I tested first and found I had a fc of about 1...figured I would hit it hard and dropped a gallon of 8.25% bleach and let it do its magic while I vacummed and scrubbed the tiles on the sides. left the pump running for 24hrs..next day things look great, I didnt test..2nd day I test and see FC has dropped to 5...hmmm, that was fast...dropped another gallon of bleach, and pump ran for the usual summer schedule of 6 hrs straight..lots of sunshine during these couple of days btw...I wait another day, go out today and do a full test and look what I see...
CYA-0? I could still easily see the black dot, not like in years past, it was 50-60 when I closed the pool in Oct, liquid was just slightly milky so I ran again and then again with another test kit to be sure.
I still have some pucks from the previous owner so I threw one in the feeder just now and am thinking maybe I need another in the pool in an old sock...any advise fellas?
