Pool went a bit green middle of this week. Started a SLAM and have been at it for about 36 hours. What I am realizing is that there is still a bit of residue that is collecting on the sides, and when swept down, it just seems to collect on the bottom and go nowhere. My numbers (posted below) have been a very good slam, and except for the gray/green collecting on the bottom, the water is crystal clear. I have been cleaning the cartridge about every 3 hours (and frankly it seems to be just fine every time). I put the pool vac in to see if it helped, and it does not seem to be sucking much up either. The water coming through the returns seems to be normal, and the pressure gauge is showing 10psi (which is just about normal for my pool with a clean filter). Any suggestions would be appreciated!
The Numbers from most recent test:
CH: 400 (This tends to the high side frequently. A yet unnamed tropical storm is headed our way, so I am assuming this number will come down.)
