So i have been having trouble with mustard algae for a while now, just cant seem to get it under control(new to owning a pool so not sure what to do exactly). 20,000 gallon pool, CYA around 80, FC a little above 10ppm. I tried bringing FC up (it was around 4ppm) but that doesnt seem to help. Should i be running the pool pump 24 hrs a day? or does that not really matter too much. Any help greatly appreciated.

Thanks
