Hello... I'm back - I fell off caring for our pool and have been on a yo-yo cycle of green and blue...
Few weeks ago, I had a dark green swamp. I mean, it was bad and with air bubbles from my system, it was a mess... Wife and 3 kids say get it together dad...
Found the air leak (o-ring on basket drain) purchased new grids 36sq and cleaned the filter twice. We have a outdoor dog (lab) and a large sand box.. Kids and dogs add sand to the pool.. Lots of sand!!
I think I've got the pool coming around and come back to see what the BLACK SPOTS are on the 6yr old surface. Never had any issues until I let it get swamp green...
I've been using acid and CL running the pump a lot to get this progress...
Total fail here - My numbers...
Ph 7.7 (drop test)
CL 5.0+ (drop test)
CYA approx 100-110
Trying to attach pictures - where do I start to attack this algae?
