I'm sure my problem has been addressed in here, but I can't seem to find it. I apologize up front if I'm starting a new thread on a repeated topic!
A week ago I had a 10,000 gallon swamp; now I have beautiful blue cloudy water that seems to have stopped clearing up. I've kept it balanced, chlorine demand has stabilized, and the filter had run 24/7 with it like this for a week, but it's still cloudy. How can I clear it up?
About 1 1/2 weeks ago (while it was still the swamp), I drained & refilled about half of it because last season my CYA was through the roof. After refilling, I started filtering 24/7, got pH to 7.2, TA to 100, Cal to 280. There was no chlorine at the time, and the water was so nasty, I didn't really trust my CYA result of 70.
Last Saturday (3/30/2013) I implemented the pool school article for turning the pond into crystal clear water as closely as I possibly could. Over the course of the day, I used 8 lbs of shock to maintain a FC level of 35. I brushed and backwashed almost every hour, and by evening the green was almost gone. Sunday I continued the same thing and that night there was less than a .5 drop in FC. Monday morning it was blue, but cloudy and it's remained like that since.
I've let the FC level drop, and have tested every night to ensure the loss is still less than .5. My current numbers are:
CYA:70? (Still getting this, but it's really hard to tell - I'd hoped it would be lower!)
This is like losing that last 5 pounds! I'd appreciate any ideas on what I need to do to clear it on up?
