So I have bought this black bloc with my tank about 2 years ago and it was already used for an unknown amount of time.
My corals used to grow but now it seems only my softies/leathers have been still looking some what normal. I’m thinking it must be the lighting if these boxes loose there intensity over time ??? It’s. 75 gallon and I’m going to look into new lighting assuming this if anyone has any suggestions for new lights ( size and amount of lights for 4’ by 2’ by 1.5’
