Opened our 22K IG vinyl pool last Wed. I waited too long (recent heat up in CT + mesh safety cover = green!)
Pump has been running 24/7 ever since, along with the LQ and periodic additions of 12.5% directly into the pool.
Here is where we stand:
FC - 6.5
CC - 0.5 (this is weird, it fluctuates between 0 and 0.5 from test to test)
pH - 7.4
TA - 40
CYA - 0 (I added some on Thursday, waiting for it to show up)
Overnight FC test - 1.0 ppm drop
The problem Im having is the water is getting clear but it seems to have a green "tint" to it. Ive had algae problems before, and as time goes on the water will turn blue/green, then clear. Right now the water looks somewhat clear but against the white colored liner the green tint looks kind of like diluted antifreeze.
The overnight FC test results are "OK" but right on the edge (FC went from 7.5 to 6.5). With 0 CYA I was aiming for a shock level of about 8 or 9 ppm, and have been good about holding it there.
Im still going to keep the FC up but figured Id ask here because the coloring seems odd to me.
Thanks in advance.
