Thank you Jim, but thats not at all what i'm looking for, i'm looking into something through the sides, something involving cutting a hole in the sides of 2 tanks and then joining them with a tube. The tube being glass or plexi in material and 4"-6" in Dia. x 12" in lengthJSchmidt said:Check out this -- a water bridge. It should do what you want.
