I am a first-time pool owner and I am sure this forum has saved me a ton of money! Thank you to everyone.
Passed the OCLT with no loss at all
The pool started to get cloudy just over a week ago with a green tint. Came back from a week out of town to find crystal clear water with a fine green silt all over the bottom of the pool. My dolphin robot made tracks through it like pressure washing a dirty driveway. It also blew a green cloud up through the fan like smoke from a chimney. It has a very fine filter on it that usually catches everything.
I cleaned the sand filter, which had new sand already. The green flowed out of the filter while I moved around the hose for about 20 minutes. I had back washed too. Added 100 lbs of sand for good measure.
Still green. Still cloudy. Not losing chlorine at night. There doesn't appear to be anythimg different as far as tree debris or dust on the furniture that would indicate an addition of dust to the pool. I have read maybe 50 posts on green dust but can't find a solution. The water was crystal clear prior to this with the exception of one algea episode about a month ago when I got cocky and let the FC get too low. A SLAM fixed it right up.
Is it possible that I have accumulated dust that is to small for the filter or the robot? Should I SLAM it just in case? Thanks for your help.
