i have a few freshwater tanks and wanted to try out a saltwater tank, really i have no idea what i need, and how small of a setup i can amke i have a 10 gallon tnak now that i dont even use i was wondering if i could use that and just get a clownfish for it or somehting to try out saltwater, what would i need to do that, right now all the tnak has is a aquaclear mini, and a 100 watt heater, and a nonflourescent hood, thanks
