It is chlorine levels and not CYA levels that allow algae to grow.

Bottom line is --- if you have adequate chlorine, you don't get algae despite rain or what your CYA level is.

What kind of algaecide did you add?

You can read other posts. If you log out first, you'll be able to see the entire forum. We had hoped to get caught up this week with getting all the new registrants processed that have come on board lately but with the passing of Ben's dad on Sunday, it is going to be a little longer until we are able to do so, unfortunately. Hope you understand.

We are glad to have you join us, however!
