I will have 40G breeder as my sump/refugium, I would have gone bigger, but I need it be under the stand as I have no more room in the house, or out. I will be using an ATI bubble master 250 skimmer, as for my lighting, I'm going to go with 2 8 lamp tek light fixtures. I like there sleek look. It should look decent I believe and no, I have not tested the tank for leaks, I forgot to plumb the last 4 closed loop returns in the back of the tank I thought I did so last night, ha guess not.
