Ok so it Is upgrade time got a killer deal on a used tank. I am upgrading to a 200 from a 92 gallon bow front. My biggest question is how much water from the 92 should I put in the 200 all perimeters are really close to spot on my kph floats a little 8-10.4 which I hope the larger tank will help stabilize. I hope not to run a full cycle once it is all set up, my fish will be in a quarentien tank for a day or two but the corals are going to be a strait transfer and I don't want to loose any of them. I am using all RODI water and coral pro salt. My coral collection consists of 30 or so small colony's and frags of SPS and LPS which I like the mix of. I am doing a very lite sand bed with about 200lbs of rock. My sump is a converted 55 with a large section for refugium. Please post any comments that may help me out in this endeavor.
