No other than bleach.. At this time I can't see the bottom due too the cloudy water. I believe I have dead algae that may be the cause. I run my pump 24/7 it is a sand dollar with a 1.5 hp pump.. This is the first year I have had this problem. The sand filter is in it's 3 year.. I backwash bout every 3 rd day. I also have a main drain. I run my manual vac. on waste and see a little green come out. I also have brushed the bottom of pool.
