I have three display tanks hooked onto my sump. This one, an anemone and lps tank, and a zoanthid and chalice tank. Lps tank is another 40 breeder and the zoa tank is a 90 tall that we just upgraded to after our shallow tank cracked. I think total gallons is around 200. Here is a link to that tank

Lighting
I ended up settling with 6 t5s and a reefbrite after playing with leds and led and t5 combos. They sit about 6 inches above the top of the tank and I just added the last ones a week ago. I use a Hamilton ballast to drive a coral plus and a blue plus in the middle with the reefbrite and a icecap 440 to drive two ATI actintics, one aqua blue special and another coral plus. The icecap goes the second coral plus a poker look which I like too.
Filtration
I use a life reef 4 foot skimmer with a skin's 181 body at the top to help transfer the bubbles to the top better. I love the mazzie injection. I run it recirculating with an iwaki 55rlt recirculating it and a mag 7 supplying it.
I have the sump full of live rock and a korilia 8 to keep detritus flowing to the skimmer, which is also a 40 breeder.
We use a 40 breeder for a lit refugium under the sps and lps tanks full of rock, soft corals and macros that drains back to the sump. The refugium has only the return flow going through it, which is maybe 800gph.
I run rox carbon and regenerate my gfo which I run in an upflow reactor. Carbon stays in a mesh filter bag next to the korilia 8 in the sump. I am slowly working vinegar into my system now.
I switched from dosing pumps with b ionic back to a calcium reactor and kalk again. I do not care for the dosing pumps as much and think I get better growth with a reactor and kalk.
Feeding
We feed a variety of food from pe mysis to flakes and pellets. We feed a lot of food and have about 25 fish and still need to stock the 90 which has 3 in it now. We use selcon, vitamin c, and other food supplements soaked in our frozen food daily.
I feed random coral foods every now and then but probly don't need to.
