I just upgraded my closed loop on my 130 to a Dolphin Ampmaster 2100 with a version 4 OM 4 way. What a difference in water movement now, no more dead spots. You'll be happy with that setup. I was fortunate to all ready have a 2" bulkhead in my tank for the inlet side. I just had to do the four 1" returns, one to each corner of the tank. No bulkheads there though, just overhead drops into the tank. Looks like your going to have a real showpiece of a tank.
