Hi All, I have a pair of Eheim Ecco Canister Filters. The flow is way high for my 29 gallon tanks. I've been told that I can slow the flow by tamping down the lever on the outflow valve. That does sound like it would work but the stuff I read online seems to suggest there is something else to do to turn it down. It also makes me wonder if turning down the output valve could labor the motor. Do you have any idea how to turn down my Eheim filter? Thanks Shango _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
