Mustard Algae - Help!

[spbb05]

Thank you Ben. The pool looks a lot better and I'm not seeing any more algae.
I retested the CYA as recommended and its 160.


I have more questions about stains/calcium build up on the floor and doing a partial drain to drain reduce cya and CH.

Can I ask on this thread or should I start a new one?

Thanks again!

+ Stains should be a separate thread.

+ Your CH level is not necessarily a problem; don't drain because of that.

+ Your high CYA is not necessarily a problem; it can actually make winter maintenance easier. Once your pool is algae free, you'll may be able to add chlorine just 1x per month.
