View Full Version : Ideal lighting for chalices/LPS

I have a 70 gallon marineland cube (30 x 30 x 20)

I currently have a maristar MH, which is an awesome light but since this tank will transition from a mixed reef to a lower light reef, I wanted to go with less light.

I've found that my chalices bleach on the sand directly under the light.

I was thinking of a 6 x 24 sunpower. I figure that would be just enough light for the highest light guys but not too much. I think a 4 x 24 would be too little light at the edges, though I could do that and keep some zoos at the periphery. I want to keep the front 3-4" completely clear of corals and also keep the sides clear so the "coral" footprint is about 24 x 24.

Any other recs?
