blue sponge

[fullmonti]

I would like to get a blue sponge for my non-photosynthetic tank. Obviously there would be enough food, but would a two tube T5 light with a super actinic, & fiji purple bulb be enough light? I could put it near the top, but that still isn't allot of light for a photosynthetic critter.

Be careful with the blue sponges they can be very tricky. I tried one with high light and high flow and still lost it in about 4 days. I have 2 nps gorgonians in that tank a bunch of turnicates popping up and it was still not enough.
