Does it ever feel like you vacuum the same algae over and over again? I just moved into a new house with a pool that was very green. This forum saved me from a ton of frustration. I now have a near crystal clear pool. Once it turned blue it was a ton of bleached dead algae in it. I floced it and that helped a lot. I have now been vacuuming it every day now for a week and there continues to be algae settling on the bottom, albiet less every day. The first time I vacuumed, I could actually see algae being pumped back into the pool. Do sand filters really work that badly?
I backwash nearly every day and its getting better, but is there some tricks to minimizing the number of times I have to vacuum the same dead algae? Should I put a sock in the pump basket? I find it depressing that a sand filter is really that inefficient.
