Forgot to tell you guys what happened. I knew I'd have to take the center of 3 front braces out to fit the sump in. So I try...And it doesn't fit. No problem, I'll just remove another one it should fit fine, the piece of polystyrene cut to the tank's size fits fine. Try to put the sump in...It doesn't fit. After getting pissed off and frustrated for a few minutes I measured the sump, it was 50mm longer than it was supposed to be. Still will fit IN the stand, just won't be able to get it in without removing all 3 front supports. So, I go and try to remove the third and...It looks like maybe the previous owner tried to drill out the screws and gave up, end result, Can't remove that one. Had to get a friend to give me a hand lifting the tank off the stand soI could try dropping the sump in through the top...Doesn't fit. After hitting my head on the wall for a few minutes I managed to rotate a piece that runs along the front from left to right around(Rotating the third front support in the process) and give me just enough room to drop the sump in. So, now I've got about an inch of free space on each side of the sump.
