I started running the filter this morning, and have blueish, cloudy water, with a BUNCH of small particles in the pool. I can't see the bottom, but I can see shadows where leaves are settling. Basically when we took the cover off there was a hole in it and green, nasty water went in the pool. I've been getting leaves out all day and I believe I've made a pretty good dent in them because the brown shadow they are creating on the bottom is getting smaller. I share all this to set the stage for my question--psi on my filter is running about 15 and has not risen more than 4 all day, but the return flow decrease to about half over a 2-3 hour period. I can backwash and the return flow goes back to normal. The pool is skimming, but since the stuff in the pool is so small I not sure I can gauge how well. What are your thoughts? I confess I have backwashed to get the return flow going again, but now I am rethinking that.
