Keep in mind that the sand filter will work and is all you need. Vac and backwash are needed when the conditions are a mess. My pool is 40 foot from a hay field on one side and 150 foot from corn on the other. Along with a few close trees that drop a copious amount of leaves during storms. So yes your sand will get your water clear without the DE or zeo or slimebag or cartridge upgrade.
filter 24/7 with skimmers working properly.
Do you have an automatic pool vacuum?
So here's my problem; when I run the filter, however it's circulating is pulling all the junk down onto the bottom of the pool. I've had a CC of zero for weeks now. I keep my FC high, and it averages between 6-8 and my CYA is 30.
But EVERYTIME my filter runs, I get junk settling on the bottom of the pool. The sand filter system has effectively been completely rebuilt (except for the pump itself). If I don't run the filter, no problem. The water is always clear, its just dirt, debris, and the occasional left or pollen stringer sink to the bottom.
I agree, the sand filter gets my water clear. But it dumps Crud on the bottom everytime that needs to be vacuumed. When I opened my pool this year it was green and full of leaves and junk(cover ripped). Yes, my filter properly helped turn my green pool cloudy, and then to clear.
If I don't run the filter, no problem, water stays clear, no junk accumulating on the bottom. If I run the filter with the slimebag, barely any junk. Maybe one small spec or two the size of a quarter, and a leaf or two that's fallen in. That's acceptable, IMO.
