Great job man, looking good! I can get you any reeflo pump that would run everything that's external if you want. This way lots of the heat can dissapte in to the air instead of being absorbed by the water. I like the hammerhead, only uses 3 amps but can put out 6000 GPH. What's cool to is that if you put a ballvalve on and throttle it back it actually uses less power. For my new tank I actually got a reconditioned hammerhead and it was waaaaay cheaper.
I never updated the return pump situation. I have since put a valve on the Mag 18 and it runs my Bio Pellets and GFO as well as return to the tank, and have a Mag 9.5 as the other pump, the chiller hasn't turned on since. I also don't have as much heat anymore since I removed the mag 5 and mag 2 that were running those reactors.
