Iwaki 30 w/ Eductor on return, Iwaki 55 w/ Eductor on closed loop. And slowly added over the last few months as my corals grew: Seio (big one), K4, MJ1200 w propellor mod, and another smaller Seio.
I removed all the powerheads and added the 2x MP40w's on the Ecosmart setting.
I bought one of the very first ones they made back in 2005 or 2006 and thought it was worth every extravagent penny. Simply a great product and I'm sure you'll be quite happy with yours.
Of course the product is AWESOME - but I have so much trouble sending THAT much money to Timbo when I knew his as an inquisitive young teen hanging out in #reefs. He should be paying me for all that wisdom and knowledge from a grizzled old guy, right?
