hey guys, i have been keeping fresh water fishtanks for allmost 4 years now and i allways wanted to try salt water, i have a 240 liter (60 gallon) fish tank, i'm not gonna start off with corals, as i wanna start out just seeing if i can maintain just regular salt water fish first, so my question is what is the cost of going bare minimum to change to salt water, seeing as i dont want live coral (yet) and what would i need to keep just the fish for now? thx guys
