oh and the bugs parts were on top of the water, the debris at the bottom was a little of everything. Last year I had to vacuum to waste very little. Last year the bugs went into the skimmer and never came back out so i assumed the sand filter was catching everything. The water stayed clean and clear all last year just with vacuuming thru the filter, this year its just coming back thru the filter when I vacuum so I have to keep vacuuming to waste which wastes alot of water........and I still have dirty water! .........scratching my head, something aint right..........
