This is my 29g nano-reef that lasted almost 2 years before it was overtaken by Xenias.. that and I got a bit lazy and neglected to do what I should have done and trimmed the Xenias back. The 29g tank was very close to my kitchen and when I had the kitchen floor tile replace, the demolition sent an enormous amount of dust into the tank (and everywhere else!) which caused the levels in my tank to go crazy! The corals were stressed after this happened and started to "melt". Being my first nano-reef..
