Tank black out for algea...
How long should I black out (leave lights out) to ensure the algea prob is gone? The reason for the prob is my sump cracked on a sunday and I used tap when I rebuilt it and there are phosphates in my tap water. I know, I know ...... . Any ideas? Should the visible cyano
be gone before putting my lights on? TIA.
