Hey all.. my pool generally runs 12-18PSI.. I noticed my heater shows LO (not enough flow I am guessing) and the PSI gauge on the cart filter canister is only readying about 3PSI. I did buy a riding mower recently and accidently blew a bunch of grass clippings in the pool.. cleaned out skimmers and pump filter basket as well as swapped out the four filter cartridges with some spares I ahd.. there were no clippings in the cartridge filters, but they were a bit slimy. I am at a loss. Any idea what else might be the culprit?
The water flow into the pump seems OK I think.. see pic.
