This our 150 Saltwater tank. We made it to look built into the wall using cabinetry. There is a 60 gallon sump with a mag 24 as a return pump underneath and on the other side of the wall in the garage is a 1/2 hp pacific coast chiller with a mag 18 on it. Protein skimmer sits in the sump and we have a seio 1500 in the rocks and a koralina 3 and 4 on the glass. Im running 3 150 metal halides but ordered 3 400 watt 20k today. I also added three 20 amp circuits to our main panels to make sure we have no problems. as far as livestock goes there are 3 hippos 1 orange shoulder 1 yellow tang 2 pajama cardinals 1 watchman goby 1 sleeper goby 1 clown 1 pygmy angel 1 firefish 1 green chromis 2 blue damsel YUCK 1 royal gramma 1 fox face rabbit and a lawn mower blenny 1 cleaner shrimp and about 30 peppermint shrimp straight from Port A!
