Help!! My pool was never opened last year because we had moved for the summer. Now I have green murky water and swamp like growth on the bottom. I have tried shock, liquid chlorine, stabilizer and algae treatment. Nothing has worked after a couple hundred dollars. Had the water tested and they said the CYA was 0. I added 4 pounds of stabilizer and shocked. Nothing is working!!
Also, the pump doesn't run long before the water flow drops but the gauge doesn't indicate that it needs backwashing. It is a sand filter and the pool is 16 x 24 with a vinyl liner. Does bleach work? If I drain the water I am afraid of damaging the liner. Any help would be great.
