Hi guys im new to this for i just got a bad ass 230 gal tank with hood, lights, canister filter, uv sterilizer and some other non important s**t. It was running slat water and i was thinking of doing that but i am not familiar with slat water and i have had many fresh water tanks in the past just never one this big. I LOVE OSCARS!! i would just like some in put on what you would do salt water or freshwater. Also what kind of fish would you do if i did freshwater and could i put live plants in there with oscar type fish i have herd mixed things about plants?
