HCA: Hermit Crab Association

I was looking at a couple more advanced builds on this forum and I saw some great saltwater pools with protein skimmers, reef sand, liverock etc. I was wondering what are the basics to get started(assuming no marine invertebrates are being kept inside), and the minimum size for such a pool

You're probably looking at around 2- 3g min to hold a relatively stable cycle, but bigger is better when it comes to cycled pools. Smaller volumes, more fluctuations.


As for setting them up, best bet would be to do your own research in the reef/marine aquarium forums and read the guides there for a general how to. I recommend checking out nanoreef.com, as its a forum dedicated to smaller marine aqua so will be able to give some insight on maintaining a smaller system. There you'll be able to find a tonne of good info.
