HI. I just took a 27' round scumming green pool to clear in 3 days. I feel quite successful. I had to switch to an inherited Perflex DE filter last year and have a question regarding vacuuming. With a large amount dead algae on the bottom of the pool, I feel I should vacuum to waste but it seems it will still pass through the fingers of the filter anyway. What method of vacuuming is recommended in my situation and would it be necessary to disassemble (the 30 nuts and bolts) on this EC-60 to clean off the fingers afterwards?
