Hello-
I used a closed loop SCWD with 3/4 ID tubing and a mag 7 on my 40 gallon. it works well, but the darn mag broke when i was screwing the impeller cover back on it after cleaning. i know how to reattach the two pieces, it just snapped. i think it is a design problem, so i just purchased a eheim 1262 to run the closed loop, it just arrived yesterday, and i will hook it up and let you know... i looked at the other pumps, but didnt decided on the eheim from my combined research
