Sure, you read as much as you can, and try to figure it all out, and I guess I just assumed that the pool school math is correct, which it probably is, and ran with it... but it is probably the bleach that isn't as strong as it should be... even at 2 months old.
so, last night FC 9.5 This morning FC 9.5. i was testing PH. 7.6 or 7.7.. I then put in a gallon, half at a time, in an hour, from WM 10%. checked it 25 mins later. it was at 11.5. added half gallon of 12% from Ollies. checked it again it was still 11.5... wasn't running my pump to fast... so maybe is still mixing... may go check it before i leave for work just to see.
I am learning things may not be what I thought, and I am losing a lot less FC a day then i thought, cause the Chlorine wasn't as strong as it should be and was never as high as I assumed to begin with...
