Hello all. For a long time (since I was a kid in the 60's) I've had fish on and off again. 50 gal. was as big a tank as I have had. But for my birthday my wife got me a 185 gal. tank!! My best friend who has a 300 gal. pointed me in this direction for info, do's and don'ts. I'm going to start off with fresh water, then later once we find a house that I think we may live in for awhile (we are renting right now) then I will set it up with salt.
