That's pretty cool! Saltwater tanks are easier to care for and the fish have personalities and stuff just starts growing that you never knew you had. I used to have a 55 but got bored with it and sold it. I kick myself everyday now and regret it, it was reef ready and built in overflows, I made the refugium. Long story short, regretting selling it. I'll get some more pics but i'll never own another acrylic aquarium again. The purple coraline algea is covering everything and as you probably know, it's not easily scraped from acrylic. I'm getting a Marineland 56 column tank. I'm going to try and build an in tank overflow and filter system, I modified the one in my 30 gallon and it's working great. Also adding an RO filter for my top off tank, it will be nice not having to carry water any more. I've got an ATO on my 30 now and I wouldn't have another tank without one. Once I get my other tank going and after I transfer my live rock, coral, inverts and fish out of it, I want to get some uncured live rock and see what I get.
