Is it absolutely necessary to have a light over a sump? I put LR rubble all threw my sump but do not have a light in there.
Pros? Cons?

crister13 said:Pros: added surface area for bio filtration and more places for pods. Cons: if it catches detritus or debris, they'll break down into ammonia.

As far as lighted sump...I don't think it really matters. Bacteria are there, that's the main purpose of the rock, so I don't think light would really do much, besides more coralline algae. If you offset the light, like on a refugium, it may help with diurnal Ph shift, but only a little, like a refuge. Just my opinion, but I don't see much advantage to lighting it. Also with light, just another place to grow algae!
