Hi. I currently have a 40g mixed reef with custom sump. I love my setup in almost every way. There are two things i hate about it. 1. Hob overflow 2. Not enough room for everything i want I have a buddy that sold me a 75g with stand 40 breeder sump, 48 tek 8 bulb tek T5, skimmer, return pump and some miscellaneous stuff I cant think of them names for. Its a great deal, but its not reef ready. He agreed to drill the tank for me if I buy the overflow kit. There is a little more to this story so far but i have pictures and will explain as I post pictures. I hope this helps somebody not make my mistakes and maybe even prove that anybody can do this with a little effort, research and a possitive attitude. Here is my current tank with the evening sun shining in.
