I just received the Eheim 2213 I purchased and want to install it in the bottom of a cabinet that a 55 gallon tank will sit on. I built the cabinet myself and it has enough room ( and then some) to house the Eheim 2213. I drilled three holes in the rear of the cabinet for the electrical cord, input & output tubing to exit. While the cabinet will hide the Ehiem and other aquarium paraphernalia, I am concerned about how hard it will be to service the Eheim. Where should I locate the quick disconnects for easy maintenance?
