Last night 3 of my 4 lights went out. I have a wave point t5 fixture that houses 4 54 watt bulbs. Came with two blues and two whites. Only working bulb currently is a blue. Should I replace with what was in the fixture or some different combination (ie all blues, all whites, add some red, violet, coral wave etc)? Currently in my tank I have 2 alardi clowns a bunch of lr and sand. And 5 small coral mostly zoas and a Kenya tree.
