Will this type of Filter (which I believe is a micron filter) collect algae and hold it on the pleats. I have what appears to be light brown or mustard algae on the bottom of my pool which I think is dead algae. It does not lay a film on the bottom but collects in the wrinkles of the vinyl in bits and pieces. When stirred, it disappears. I attached a homemade vacumn to the suction side of my pump to collect it but I wonder if all i am doing is recirculating it. I also syphoned some of this into a 5 gallon bucket and let it sit in the sun for a few hours and checked it later. I could not see any of this material; just dirt. Your opinon please?
