I began the season with a green pool, it's all clear now, but I think I still have mustard algae which I"ve had since last season but never completely got rid of. It looks like there is dirt on the bottom and sides of my pool, when I sweep it it looks like a puff of smoke, the water gets slightly cloudy then it settles again on the bottom of the pool. I have kept the FC up but it's still there. I'm using granular chlorine from wal-mart as I am a newbie and I already had it before I began reading this forum and gained knowledge from all of you. I plan on getting bleach when I run out. My test kit is not in yet either, so I don't know my exact numbers, it is ordered and should be here any day now. Just want to get rid of the stuff already!! Any suggestions.
