Hi, Mike,

Thanks for the numbers. Very helpful.

With your CYA of still 90 (good work, tho) I would carefully calculate enough Cl to raise it to 25ppm. I would hold it at 25ppm as consistently as you can and I believe your water will clear soon.

A real indicator that you still got "bugs" is that CC of 1. The 25ppm will get you to breakpoint or "shock" value and get the CC to less than .5, which is what you want.

I believe you may be closer than you think. It sorta sounds like you been getting almost up there with the Cl, but not quite. Go ahead and knock it out of the park with the 25ppm. Calculate carefully (don't go too high) and add it a dusk this evening......it'll be somewhat more effective at night.

Keep us posted.
