Just got a new-to-is Biocube 32G yesterday! Woohoo! We previously only had a 13.5G so this is really going to be a nice sized upgrade for us (yes I know it is still considered nano/small lol). The tank had been up and running and I believe used for housing anemones. It came with sand, water...

Now that you own it, What would do again, possibly pay twice as much for? What is your favorite must have for your reef? Anything.. Animals, attachments, what do you have 2 of? What would you buy again without thinking?
