I started a new thread for you for your pool problem and moved your post here. That is better than tacking it at the end of the stickied thread.

Your FC of 40 is REALLY HIGH for a vinyl pool with a cya reading of 30. I hope it doesn't fade your liner. It certainly ought to kill anything that is growing in your pool!

Typically for a pool with cya of 30. we recommend somewhere between 12-15 for the FC level when fighting algae. Let it drop down to that range. Run your pump 24/7 and let your filter do its job removing dead algae.

What did you use for your chlorine? Cal-hypo? Dichlor powder? Bleach or some liquid chlorine? I'd suggest just sticking with bleach. Any idea what your calcium hardness reading is?

I'm not sure how you can have an FC of 40, a CYA of 30 and STILL have a CC of anything greater than zero, but you report 1.0.

I suspect you meant to say your FC is 4.0 and your CC is 1.0, in which case you need to raise your FC to 15 and keep it there at least 24 hours until your CC is 0.
