TRUST ME when I say start off bigger than a 10 gallon nano, I did Saltwater N00B! and I've wished since the beginning that I had started off larger. It started as a FOWLR, then it gained a polyp, that was the end of it, I've spent countless dollars on testing equipment just to make sure that small amount of water doesnt fluctuate too much and destroy my zoa's and other softies. Your in for a fun ride either way, just watch the parameters and enjoy yourself...

I'm currently building a 40 breeder with a 29 gallon sump, 10 wasnt enough...
