I never thought I would have to use clamps but it sure works better then duct tape. I wasn't able to maintain the 1/16 gap in the seams and had to settle for 1/32 which took place naturally. Doing this to both ends will make the tank slightly narrower 23 7/8" instead of 24", all except for the center brace when will maintain 24" and I don't intend to remove. I hope this small variance will not hurt anything
