Got my FAS/DPD test kit on Wednesday so I've been recording the numbers since then. Friday night I changed how I was handling the chlorine -- before I was getting it to shock level each time it would drift down. Now I'm trying to keep it above shock level so when it drifts down it never gets below shock level. With my CYA of 60, it says shock level is 18. I've kept it above that for 36 hours now. From last night to this morning my FC dropped from 22.5 to 18.5. The CC still reads something around 0.5.
I've brushed and vacuumed the pool the past 2 days. I did find a couple of leaves at the bottom but for the most part the walls and floor are clean. Started all this Thursday a week ago. Turned the pool from green to blue overnight but the water has stayed cloudy since. I've added a mountain of chlorine but have kept it at the highest the past 2 days.
It sure gets hard to keep doing this. Is it possible I've backwashed too much ? That the sand filter isn't doing it's job to clear the water ? I changed out the sand but while the water was still green. The water seems to circulate well. I did a lot of skimming by hand the first few days but there's hardly anything floating now -- a bug here and there but that's it. I keep both baskets empty.
Just hoping I'm on the right path to get this water to clear.
