What is the dimensions of your tank? I would suggest the biggest possible. My 125 is not the 6' dimensions, but its the 5'. I use a 40 breeder for my 125, but its width could be a little probelm for the 6' version I think.
Oh, yes I can. I just bought my sump and I'm trying to set everything up now. It doesn't come with instructions so I'm trying to remember everything the sales person from the LFS told me but it was so long that I can just remember the first few parts.
