Did sloppy job non-closing NC above ground last fall. Peeked under cover and oops! Brownish green. I know what I did wrong, need a little guidance on clean up. Didn't think about all details except need chlorine. Had two gallons of 10% from last fall and dumped them in 19300 gal. Added 2 more gallons 10% chlorine this morning. Got out test kit, first test FC 11, dumped Acid ...into pool for Ph! 3 hrs later, tested FC 9, pH 7.5 and CYA haven't done anything yet. Should I dump a 1/2 gal liquid stabilizer and in a few hours drop more chlorine and wait until morning to do testing. The green/brown has lightened enough for me to see, albiet barely, leaf pile in center (water 52, will use rake tomorrow). Not sure what slam FC number to use since no CYA, just knew get the chlorine in. Thanks for deciphering this and any advice welcome.
FC - 9
CC - .5 (barely)
pH - 8+++ (flourescent pink)1
CYA less than 25 (prob none)
