I had not intended to create a gorg-tank, but that is the way it ended up with the LR that I got. It's a really nice benefit to have some very large coral in there while the SPS grow up.

I feed phytoplankton every day. I'm not currently feeding zooplankton, but I do intend to. I'm pretty sure that the sponges would be feeding on nothing larger than phyto, but I've not been able to find any research that confirms that this is what the sponges actually consume. It could be bacteria.

The branching orange sponges seem to be doing OK. However, the tall red sponges are dying fast. The yellow ball sponges can't seem to fend off algae...and I have two types of other red and orange sponges sheltered in the rocks that seem to be doing fine. So if one type of sponge might be getting what it needs, some other types are clearly not.
