Algae help needed

[gregzz4]

Don't worry right now about peroxide dosing or the fact that your chaeto is dying off.
Just keep your methods going forward.
Too many things at 1 time ...
Chaeto doesn't always live.
Stick with what you are doing for the next month.
Then make changes.
I've told you many times, slow and steady and nothing good happens fast in a reef tank :-)
