hi,
This is my first post after lurking for a long time. My CYA have always been very high, about 150?, probably due to reliance on trichlor tabs.

I've since started using bleach and I also use my SWG at maximum, doesn't seem to produce enough during the summer heat (90-100).

Everyone here advocates a lower CYA and I'm tempted to drain my pool and start over and at the same time scrub my black algae with chlorine.

Does this even make sense or should I just live with a high CYA. My water is crystal clear, we use the pool very little.

thanks in advance for your advice.
J
