You are correct, John did the tank.
Chris, i am using a Hammerhead pump feed 2 returns, 1/3hp chiller and 30gal refuge located outside. Overflow has 3 2" drains feeding into a 3" pipe into the sump. All other plumping is 1.5".
I also have EuroReef RC 8-3+ skimmer and Aqual Ultraviolet 40w UV.
2 phosban reactors, 1 with carbon and 1 with phos material.
2 Tunze 6100's for flow and Tunze Osmolator and Kalk dispensor (soon to be hooked up) into my 20gal high tank i use for water top off.
Sump is ~35gal acrylic also from John.
4 250 Reef Optix3 with 2 10k Reeflux bulbs and 2 Phoenix 14k bulbs with 2 T5 actinics. Only other item i can think of is i also run Ozone into my skimmer.
