Thanks all. I did buy the tank used. I got into the hobby a few years ago with a 28 nano, within months moved to a 55, bought a house and had room for a 125. I'm already eager for something bigger! The 28 and 55 did fine, but they were also bought new. I've been afraid it may have been copper...even though all my water (for changes and top off) are bought. I change out 25 gallons each weekend and do manual top offs daily. I have 8 T5s. I change the oldest pair every month, so they oldest set of lights is 4 months old (maybe slightly obsessive, but I want to get things running). I've got a 40 gallon sump below which collects water from 2x 200 gph hang on the back overflow boxes and 2x tank drilled 1" PVC pipes. I estimate I'm cycling about 600+ gph. I have 2x 700 gph water circulation pumps, 4x PVC returns from sump, and 1x 1400 gph pump sitting in the tank creating really nice flow. As for the fish... I have: 1x Tomini Tang about 5" 1x Pacific Blue Tang about 10" 1x Naso Tang about 10" 1x Clown Tang about 5" (the alpha fish) 1x Flame Angel about 3" 1x Cleaner Wrasse about 3" The tank The sump (might be getting rid of rock down there if anyone is interested) A few happy fish with clean sand One side of overflow box plus drilled PVC pipe I suspect this is coralline

I've had a 125 gallon reef tank setup for about 2 years now. Any type of fish has thrived in the tank. I can't seem to keep any form of coral (SPS, LPS, etc.) for more than a week before its completely dead. I've noticed that snails and crabs (both emerald and hermit) last a few weeks than die too. My sump housed protein skimmer pulls out enough filth. My flow is great. My T5s are bright and changed frequently. My sand is clean. My rock is nicely colored (reds and greens). Water tests (both myself and local stores) all come back normal. I've got a few tangs, wrasses, and dwarf angels. I'd love to figure out what is wrong with it so that I can thoroughly enjoy the hobby with coral and inverts.
