I have added stabilizer it's a lil low still be not to bad. I do have the pump on recirculate not through the pump. It has gone to a really light green I did scoop out some more debris from the bottom before I added the bleach last night hard to tell if I got it all. But I'm pretty sure most is out. It has had 2 years of stuff on the bottom due to the last owner not having it running starting to think I should have just drained it. Ha. But I will give it another dose of chlorine
