My pump died but it is still under warranty. My question is, how do I keep the algae out while waiting on my new pump?? My chlorine levels are high but my PH is very low, like under 6.2. I was going to add PH up but don't know that I should now that I can't run the pump. I don't want my water completely swamp like by the time the pump gets here. This is a 6000+ gallon above ground Intex.
