Pollen or Mustard Algae?

[4KidsSwim]

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.

As a fellow northwesterner, I sympathize with anyone who gets mustard algae. Our seasons are short enough without dealing with that. Last year was the first time I had to deal with it and it was murder. Because my CYA was so high from using trichlor (no more), I had to shock at very high levels to get rid of it. I was taught, on this forum, that the only way to get rid of it was super-shocking. Polyquat is a good preventative but nothing kills it but chlorine.

Watemom, I have ignored this forum all winter (shame on me) so I just learned of your struggles. Please add my thoughts and prayers to the many that have been offered. You will beat this!!!!
