Hi everyone, new to the forum. My wife and I are up-grading our 90 gal reef to a 240 gal reef. This will be a big jump for us so we will have many questions. We have experience with a 180 a few years ago, and have had great luck with our 90, which has been running for about 1 yr. So we are moving up to a 240. Below are some pictures to document our beginning. The tank has pre-filter boxes in both back corners. When we bought the tank used it was drilled in all four holes for half inch bulkheads, way to small, they were using all four for drainage. They must have had over the back return, as we never saw the tank set-up. In one hole the glass was cracked and has been repaired. I was limited on the size that I could safely drill it larger. We opted to drill all four holes to fit 1" bulkheads, and will deal with any drainage problems later. I have ordered a Sequence dart pump, and will maybe use it for skimming also ( please advise ). I will keep everyone updated with pictures. Thanks for all the help We will need.
