corro, I currently have a Mag12 on my return for my 60 gallon. I had it T'd going to two locations, but since the flow was so weak i had to shut one side down. Now its going to my seaswirl, and thats doing so so... So i just picked up the oceansmotions squirt to enhance the flow rate in the tank. Having a cube makes it difficult to get the flow to all the locations of the tank! I dont know enough on closed loop systems, i've read tons of posts but still not sure how i should set mine up. any suggestions would help! thanks in advance! hows your tank going?
