LOL... I did this about a year ago I see if I can get a picture for you. My set up had a 180 with built in overflows and a 75g for my planted tank. The 75 was back to back with the 180g. so thats the main differance what I did was.
I got an old hang on filter that pushed 300gph drilled holes in the backwith another drop box (DIY), the 75 was at right hight for the drop box to overflow into the 75. I also hooked up 2 powerheads at each side of the 180 linded them to pump into the 75g. The 75 had 2 coner DIY overflow boxes and a canister inlet in the bottom center. The overflows from the 75 went to the sump filtered and went to the 180g. in the 180g overflows, filling up and pouring into the tank and the canister return lines also went into the 180g.
Crazy as anything but it worked so nice. just had to keep an eye on the water level in the 180g.
so try what you can, you be amazed. Just if you want the plantedtank to feed of the 265g you have to get all the water out ofthe 265 to the planted tank and then filter. and dont get jumping fish for either.LOl
