ok...so ive been testing the water at least 2 times a day. the ph is staying at 7.2 and the fc is at least 15. i tried diluting it a little more and multiplying by 4 and it was still very yellow. the pool cleared up dramatically where it is now clear, but still a little green. ive been adding 1.5 gallons of bleach daily, backwashing daily and vacuming daily. I got up A LOT of algea. so, how much longer do you think before the pool is blue again? also, how do you guys feel about the phos free solution to keep algea from feeding? thanks for all of your help.
