I also use a shop vac for mine on occasion :) Just turn the heater and flow off said:
Yes i do have sand in the refugium section of my sump. Crud seems to collect in there on top and in the sump where it drains. Im not talking like tons of crud, but i can see it and overtime it could become a problem. i was thinking of putting some hermits down there but didnt know if they would do any good."]
If you have sand, a cuke is a good worker, though in a sump, you want to be careful since they will migrate into the other chambers and a cuke and pump don't mix well. If it were me, I'd get myself a couple of 1"-2" conchs, tonga or flordia fighting conchs. Just keep an eye on them and if they clean it up, drop some sinking algae pellets in there from time to time.
