Dubosity's Thread: Lost in Cloudiness/Mustard Algae Hell

[Watermom]

Stopping the pucks will not lower the CYA. The only way to lower it is to exchange water. Having said that, you do need to stop using the pucks, though. Otherwise your CYA will continue to climb and you certainly don't want that. Definitely go with bleach. Like Ben said, if you don't want to do a partial drain and refill, you can just run higher than normal chlorine levels as outlined in the Best Guess chart in my signature below. You have to do one or the other. Otherwise, you're never going to get this pool under control. High CYA without high chlorine = algae blooms that never go away for good.

all righty then :-) I will definitely do a partial drain/refill, stop using the pucks, and switch to bleach. Thanks a million! (I also ordered the K2006 kit...through your link so that you guys get some of the $...you deserve it!)

Just a note about the suits --

I *think* that the bleaching effect of chlorine is ALSO reduced by high CYA, so the suits *may* be fine. Chem_Geek is more confident of this than I, and he has a better grasp on the analytical side of the chemistry than I do. I've got some niggling memories of conversations years ago with one of the pioneers of industrial bleach production that make me a little less confident.

But odds are that your suits will be OK, even if you can't go au naturel. It's just I'm not complete sure of that,yet.
