So i have decided to turn my small 10g fresh water tank into a small fish only saltwater tank im just wondering what exactly i need? everything i found on the internet is for 55 gallon and above and not just fish only, i have the tank, hood with lights, heater, aqueon power filter 10. I know i would need to get aquarium salt and the device to test salt level ( cant think of name off hand ) and the fish of course, what else would i need? do i need to get a new substrate other than the black gravel i have now or no?
thanks
