Just for the record, the canister was an Eheim 2250 with an Eheim 1060 pump (not the sock pump for that filter, which is a 1253 pump). And the 1060 was the pump I first used on the sump set-up. sh _______________________________________________ Aquatic-Plants mailing list Aquatic-Plants at actwin_com http://www.actwin.com/mailman/listinfo/aquatic-plants
