Thanks -

I'm losing almost 5ppm FC overnight, redosed this morning, and I lost 6ppm during the day (I was gone) so I have to assume mustard algae. I added more bleach tonight and will check in two hours to make sure it is up to over 15 before I go to bed. I'm finally getting a CC reading <.5, which is some indication of success I suppose.

Since my CYA is around 25, I'll keep my FC at 15 until it holds on its own. I really want to up my stabilizer to 40 to combat our hot sunny summer days here, but I won't until I get this taken care of.

I guess I'll just keep doing the "Pool Forum Algae Removal Formula"...

but first I think I'll buy stock in the manufacturer of WalMart bleach.
