aggiereefer12 is right, i dont have a sump, i want one and am willing to trade my 55gallon for one and a refugase?
After you played with it, i tried it and it seemed to be level just off by a little bit like 1 or 2cms but it still leaked when even i made it level.
Finally, i just asked my dad to seal it and when i tested it, it didn't leak.
I'm just waiting till tomorrow to actually test it out.
