Any progress?

Yes, I've kept it at about 12ppm for several days and brushed 2/day. The algae appears to be gone. Since I've started this its been cloudy & raining so I dont know if the cl will hold during a sunny day. I'm keeping my fingers crossed.

Can you recommend a good CYA test kit? I tried retesting after the pool store. They got 50 and I got 190+. I was using their number to base my best guess shock.

Thanks for all the help.
