Anyone run a sump on a freshwater tank?

[Delphinus]

Thanks for the replies. So far, mostly echoing my own thoughts.

How do MTS fare against clown loaches? My clowns make pretty quick work of any snail I put in the tank. I have found a few that seem to hold their own for a while, there is this sort of "bumblebee snail" or something like that but a) they next to useless as far as detritivores go, they're only pretty to look at, b) they appear to be only semi-aqautic, hanging out at just above the water's edge most of the time and c) I eventually find their empty shells on the bottom next to a smug looking loach...

Also ... whenever I've gone looking for them my LFS had never heard of them when I asked about them. I once found snails in their tank that coul dbe MTS, but they refused to give me any because of that particular snail's (do't know if it was MTS or not) propensity to become a nasty plaque of a zillion snails in a tank. I told them, likely not a problem with my escargot-loving-loaches, but still, they didn't want me to have any. Oh well.

What are people using for live food in sump/refuge grow-outs? Most freshwater live foods I thought were kinda gross, like blackworms or mosquito larva. (Hmmm, mozzie larva inside my house, now THERE's a great idea... ;) )
