Hey everyone if u can share ur worst electric bill. I'm building a 300g tank and I have a friend with just a 180g, he was just telling me his electric bill was 450 bucks this last month. I'm doing fresh water so I won't be as bad as him, he has saltwater so he has very high output lights for his corals and such. He also has reverse osmosis and all which I will have too but damn 450 a month may turn me off
