After keeping freshwater tanks over the years I finally decided to start a reef tank. I had a couple 40 breeders that I was going to use but I saw a 60 breeder and decided to go that route instead. Figured the extra foot of length would open up more options in the future. I purchased the tank the end of February. I also purchased a modular marine 1200 gph overflow. First step was to drill the tank for the overflow and 2 returns as I am going to run 2 return pumps. I was nervous about drilling the glass but it ended up being easy, although it was a very slow process.
