Ok here is my dilemma. I have a 210 with a 40gal wet/dry sump that I've had for years, but its so much hassle pulling the filter pads out and trying not to make a mess and in the three years I've used it I have never found a simple way to do it. Also I want a little more sump volume. I bought a 55 from petco on the $1 sale (I know I need a bigger sump but to squeeze anything more in there id have to drain the tank and slide it away from the wall to put in through the back of my stand) I have an ETSS skimmer but it is external and returns through the side of my sump (picture attached) would it be a good idea to drill the 55 on the side or is there another way to get the water back in without dealing with all the hassle? Also what size filter sock(s) would you run? I planned on setting it up with the filter socks and return first, fuge, then the return pump area last but it has to be big enough for my mag 18, mag 12 and my mag 7 to fit in for the pump side unless I run the water deep enough to stack the pumps on top of each other. Also on that note how deep should I run it since ill be doing a fuge?
