So I have a few questions for you all. Im going to be building my own bp rack, and I bought the 23" long sterlite tubs (28 qt) but I was wondering if they were long enought or if I should get the 36" tubs. I have seen both used but was wondering what you guys thought. Also, I plan on having it built so the tubs go in "long ways", and most people use the 11" heat tape running along the back, with their tubs in "short ways", so less of the actual tub is covered. So if I put the tub in long ways it would cover over half of the tub, so do I need the 11" heat tape or could I use the 4". Thanks in adavance.
