Failed my first attempt at a SLAM to deal with recurrent algae in corners of our pebble pool. Passed all tests and things looked great a few days and then it was back. Small amounts of yellow/green that collect even with frequent brushing. Easily brushes off, makes a cloud. I also have some gross stuff coming out of spa blowers that I attempted to photograph. The photo is too large to attach but they are brown slimy flakes. I lowered the ph 7.2 and am restarting the slam. It is possible to clean the spa blower?
