Looks like you have 4 20w lights. That's 80 wats, 2.66
wats per gallon. That's quite low. You want 3 to 5 wats of
light per gallon. 3 being on the low side, and 5 being
where you want to be. I like going a little higher like
6.6 wats of light per gallon.

The more light you have the more vigor your corals will
have, and the better chance they have for healing up if
they get dammaged, and better chance of fighing off infection.
