I combatted an algae attack and water is now balanced. When I tried to vacuum up the dead stuff at the bottom, it went right through my cartridge filter and back into the pool. I actually saw the debris shooting back in through the return jet. Gross. Any suggestions for how I can suck up the junk without returning it to my pool or wasting water? We're on restrictions and my water is perfectly balanced, so I really don't want to vacuum to waste. I'm open to ideas about a good automatic cleaner, too. Any help/suggestions welcome! Thanks.
