I am new to the hobby. Setting up my 1st saltwater reef tank. I have a 45 gallon (36"x 12"x 24") tank which is mounted in a wall. It was already existing (formerly freshwater) when I moved in. I have the current loop system w/ 2 of the small eflux wave pumps. Long story short, Due to the wall and my set up, I can only use the magnet to mount one of the 2 pumps. The other needs to be either glued or epoxyed to the inside of the glass tank. It needs it to be secure, yet able to be removed without damaging the glass (in case I move in a couple of years). I would appreciate suggestions on what to use... Also need suggestions on the best thing to glue or epoxy plastic with. I am making a DIY refugium from an Aquaclear 70 filter. Thanks in advance for the help!
