Hi, I am a new user to this site. I wish I would have found it 30 days ago. I am struggling to get my pool in good working order this season. Algae is the biggest issue. However, I did replace the pump motor, DE Filter grids, and last weekend had to replace the booster pump seals. Everything is functioning correctly now, but I can't get ahead of the algae. Finally one of the guys at the local pool store told me my stabilizer level was too high. He didn't tell me how high it was but that it was too high. He instructed me to put 8 lbs of shock in on Friday, backwash and brush again Saturday and drop 4 more lbs of shock. Most of the green is gone, but there are still two areas on the bottom of my pool that are mustard color and three areas that appear to be dark brown or god forbid black algae. Yesterday I drained approximately 1/3 of the pool and am refilling now in an attempt to lower the stabilizer levels. Once the pool is full again I will retest and get a more accurate level. On my way to Walmart to buy bleach and an HTH 6 way test kit. Any recommendations are greatly appreciated.
