Oh my goodness!! Took the cover off - green swamp - added (5) 121 oz 8.25% Clorox two hours ago - just tested and showed 1.5ppm!!!!! Adding 4 more now. Can this really be happening?? Been scooping out chunks of green slime for 2 hours - using kneehigh hose in the skimmer - getting clogged every 10 minutes - rinsing and replacing. I'll have to take the hose off skimmer for the night - will my filter blow up???
