ok so next weekend I am going to break down the 75 and put up the 125. I am going to use half of my old sandbed to seed teh new sand bed. I am going to take my rock from my 75 and put it in my 125. I am also going to use as much water from the 75 into the 125. I am going to grab turbo start just in case I have a mini cycle. I have to put my fish right into the tank. I have no where to put the coral or the fish. I figure with the wet skim going and all the bacteria from the rocks an dsand I will be fine. any feed back or advice will help me . thanks
