So I'm new to having a sump and overflow. Now I see a hundred fanworms and pods crawling everywhere in the overflow box. I figure its about 5 gallons so its bigger than the refugium in my sump. (90 gallon display, 20 gallon sump) Does anyone manage this area or is it survival of the fit enough? Does anyone put anything in there on purpose?

I have a coast to coast overflow that I converted to an in tank refugium, when I decided to go without a sump. I put chaeto, ulva, grasilaria and other macros in it for pod habitat as well as nutrient uptake.

You might try adding macro algae as well to yours. Does it get good light? If so, give it a go. If not, you may find sponge in there one day. Either way it benefits your tank.

No light for me in the overflow box so its chitons and fanworms now and probably sponges and aiptasia taking over soon. I've seen my nerites move in and out of there. I have a side overflow and have a pretty good view into whats in there. Its definitely going to have its own population of critters.

I was curious as to what most people see inhabiting that area.
