Closed loop

[DJ88]

Bruce,

Ever unplug then plug your MAG in repeatedly? Try it. You'll know why I am saying this when you do it. I know where your tank is in relation to your couch. :D

I am doing a closed loop with two MAG 7's in my new tank. By the time you take into account the bends of tubing and such I bet you might get 100 GPH out of your MAG2. Not worth it with a pump that small. Go for Mag 7 and put a ball valve if it is too much.

By the time I am done I will have one sea swirl(only beacuase I have it) and three 1.5" PVC outlets. One for a MAG7 and the other two from the MAG18 return.

Don't spend the cash on the sea swirl. Buy two MAG7's and run them closed loop into large diameter PVC outlets. Saves you the cash.
