I lived on Bull Shoals lake in Arkansas and in the spring water via is 60+feet. There are sunken boats and all kinds of stuff. And it's 220 feet at its deepest point.
At one time had 5 fw tanks going, reduced down to 2 with a hospital/qt. Now going completly salt have one tank that will remain fw until friends tank is ready for the angel pair that I am giving him.
Currently have 3 Salt tanks.. (QT/babby sitting a 55gal for about 3 months.. and my 75g tank) I really would like to get a 125 and call it a day.. the 75g I have has glass scratches real bad.
My wife is away for 30 days with the military.. so I get lotsa time in the evenings to watch my tank grow algae.. since that myh eel and my LPS corals are all thats thriving.....
