well...sigh... im not good with wood and thats why im a phone man. I cut everything down to fit my two 10s, everything was going great. I got it all put together and its pretty level and square. I put the 10 on top fits great. I moved it to the bottom, and the darn thing dont fit... i forgot to include the vertical supports and im about 3 inches to narrow.So now i dont know what to do. Any suggesttions for the sump is it nessesary or can i just hang my skimmer on the tank?
