This is my first season using BBB, bought the TFP test kit and am using it. Read Pool School and Turning your Swamp into Oasis.
Upon uncovering (mesh cover), pool was green, green, green (a bad pollen year with lots of oaks and pines around pool area).
Started pump and ran it 24/7. After getting ph = 7.2 and TA = 110, starting shocking while adding CYA in sock/skimmer - CYA was 0. Used about 45 lbs of Calcium Hypoclorite (left over from last season) to start with - Ca level was 270 so I wasn't worried about using it first. Then switched to 6% bleach. My target FC shock level was 10. Brushed sides and bottom, ran Polaris. Got the green out in about 2-3 days following Turning your Swamp into Oasis instructions. Numbers were great (FC: 3-5, TC: <.5, pH: 7.2, TA: 100
Ca: 290), except CYA still not above 10 - but I wasn't losing that much FC in the daylight and was holding steady at night. I'm still bringing the CYA up slowly. (Pool store lady said to go ahead and shock with low CYA).
After another 3-4 days, my gray-white couldiness was not dissipating and Sand Filter back pressure was not rising any more. Tried a clarifer (left over from last season). No effect. Tried another clarifier with flock and it maybe helped a little - but while vaccing to waste I kicked up some more pockets of algae. AHA! Went back to shock level of FC, brushed and vacced like a madman. After one day, FC holding shock level overnight, with CC <.5. BUT......
Pump still running after 2-3 days and cloudiness STILL not getting better. Numbers tonight - FC: 3, TC: <.5, pH: 7.2, TA: 90 Ca: 290 CYA: <15.
If anyone is still with me after reading this novella, any ideas? Oh yeah, I replaced the sand 2 years ago. I'm thinking about replacing the top 1/3 of the sand to see if that will help.
Thanks.
