So I'm trying to plan for my next build. I'm going to be having my display tank against a wall where on the other side of the wall is the interior of my garage. I'm going to mix my salt and water change water in a tank that's in my garage. Obviously, I'll have to run a hose from the water change tank through the wall and into the interior of my home where the tank is. Since i'm going to be cutting a hole between my garage and the interior of my home, I have to find a way to cover up the gap between the hose and the sheetrock. I don't want any mice or roaches to be able to get in. Just wondering what you guys use to cover the gaps. Is there some kind of rubber grommet or something else that you use? Thanks!!
