Had some algae problems because of my lack of maintaince. Shocked pool added algacide. water is clear and clean with no signs of algae in pool.
Problem is I have 2 skimmers and they have some type of a algae scum that forms inside of them along the water line. I can wipe it out and regrows fast!. I have shut pool filter system down at night and filled with some shock also wiped out with algacide and NOT taking care of it. I clean them out regularly each day some times 2 and 3 times a day . Shallow end gets more build up than deep end. Appears in color blue green and grows quickly reappearing within a short time after being wiped away. I have noticed that a beetle floating in skimmer it is growing it on the outside of the beetle body TOO YUCK! Is it a bacteria? I need help and appreciate any suggestions. I have a sand filter 30,000 gallons. Water temp like 84 degrees. 20x40 inground. Thanks
