wheatgerm;4269237; said:i have been told you can break your glass very easily if you lay it on its face and happen to slightly drop it onto the wood when getting your fingers out. is that why you placed it in first while standing up then layed it on the face?
STOP! Dont waste your time and money on building a plywood sump. I built mine and it worked OK until it leaked. I never really liked it too much to be honest. My 50G Rubbermaid water totes where much cheaper and much much easier. I had about 7 coats of LR on my sump and still got a leak. Memember that every wall/divider you put in the sump will have to be screwed from the outside and then covered in LR on the inside. Imagine applying LR to the bottom of a divider that is sitting 3-4" off the bottom of the sump. Go toward the end of my build where I have pictures of me cutting the sump out....maybe that will help change your mind. Think 50G Rubbermaid totes with 10G Tots inside to hold filter media. I have 2 of these under my tank!
