For over three years I kept a 75 gallon reef tank but, two year ago my reserve unit got sent to the dessert of Iraq and I had to give up the hobby. Now I'm back from hell and want to start an aggressive tank. I still have my tank as well as the berlin skimmer and some return pumps but this time I think I will want a larger tank. So Can you guys help me built the ultimate 125 tank possible? Please give as many ideas as possible.
