This is both a new type of tank for me, and my first time posting my build on a forum, so wish me luck leading us on this journey. A bit about me. I have had tanks of various types, sizes and shapes for almost 50 years. I've had a 400 gallon marine predator tank ... a 3 gallon iMac fresh tank...A 12 gallon nano reef...A pie-shaped tank. I also have two dogs and a job that keeps me busy. I moved into this house last spring. I thought this spot between the support pillars separating the living room from the kitchen area would be perfect for an island tank viewable from all sides. The distance between the inside of both pillars is 68". Had a structural engineer check the structure underneath while inspecting the house and got a green light to proceed. By the time I was settled into the house it was the end of the summer. I had been thinking about the unique needs of an island tank. How do you move water in and out of the tank? How do you provide power? I realized that I would need the overflow to be in the center of the tank but was concerned about its footprint. I knew the tank was going to be 60" long - it was not worth the cost of customizing for a few additional inches. I had tanks that were 36" tall in the past, and was not going over 24" this time. Given the space the tank could be either 24" or 30" deep. In doing research on tank builders I came across Custom Aquariums (had purchased Glass Cages before with positive results). What intrigued me about CA besides they built tanks like, well...tanks, is their unique H2Overflow and concealment column. They can run a 1-1/2" overflow and two, 3/4" returns through a single 3" sleeve, taking up much less precious tank real estate. I was skeptical of their H2Overflow and if it would really work as advertised. There were not many reviews but the few I were able to track down were positive. I've always been a bit of an early adopter, so I went and placed the order in the fall of 2018. With the holidays it was not until January that the tank arrived. I had gone and ordered not only the tank with their concealment column, but also a 36" tall stand and their modular HDPE sump system. It was packed amazingly well, and with a little help got it in place. Next, the slow process of getting the plumbing and electrical systems set up...please be patient.
