Hey everyone! I have an issue with dead algae being recirculated back into the pool. I know this problem could be avoided by just keeping the pool algae free and not having to bomb the water from time to time, but here we are.
It's a brand new sand filter, a TR100, with brand new sand. The pump is an old workhorse that I don't know the real details of. It's a 28k gallon in ground plaster pool. The system used to have jets, but I pulled all the jets and am now running a 4 wheel Hayward Aquanaut, so the jet holes are now serving as the returns. It recirculates so much sediment that when I turn on the pump I can watch the returns pump gigantic clouds of dead algae into the pool, turning a relatively clear pool into a turbid cloudy mess.
Can this be caused by cheap sand? I am suspicious that the company who installed the filter used very cheap sand as I sometimes notice filter sand at the returns. When I backwash I definitely get lots of nastiness out of the filter, so a filter deep clean is in my near future plans. My only other thought is regarding air in the system. I definitely have an air leak I need to chase down that sends air through the returns. Perhaps air running through the filter forces debris back to the return side? I didn't think the air leak was a big deal and my pool guy told me to not worry about it so I haven't taken the time to really diagnose it.
Any suggestions beyond deep cleaning the filter would be much appreciated.
Cheers!
