gordy back. ok today i can finally somewhat see the bottom of the pool. still cloudy though i think its improving. I don't know what happened. fc has dropped to 20ppm, cc still 0 which i think is normal due to the first sunny day in a week .i didn't change anything since the last post. today i felt a little scientific and decided to really look at my water. took a mason jar and filled it with some pool water. looked at it with magnifying glass, i can see very tiny particles floating around, maybe dead algea? even so isn't the filter supposed to take care of this? i think it is but very slowly. I've had water turn cloudy last year after rain, but after a good shock, presto, crystal clear. maybe its time to go cartridge. anyways thanks for the responses i'm going to try the DE trick and see if i can get any more improvement.
