So i have a HOB DIY fuge with chalupra(SP) in it and i was wondering if i really needed the filter media (sponge) in it? Can i just take it out?

The only reason I have a sponge in my HOB fuge is to catch bubbles.

Id say the only reason to have the sponge in there would be as a bubble trap after a protein skimmer. Otherwise it's just trapping plankton that would be better off in the DT...

I have a cpr hob and I dont use any sponges. I think that a sponge would hold up the flow of pods in to the Dt.

Where was the sponge?

Usually sponges just filter out the plankton/pods that you're trying to get into the main tank. BUT, I need to at least address that having a sponge IN a refugium can be a great place for copepods to breed.

Not in that 1st lil chamber but theres like a hole on the other side!!! I just covered the whole with the sponge!
