I went out and bought the rack from walmart around 18 bucks. It is a bit flimsy before its put together. but it holds my tubs pretty well. I am using 50 qt tubs with hardware cloth on the middle of the lids and I currently can hold 6-8 50 qt tubs. Depending if i want birthing tubs included on the top. Its working really well for me. the only negative is i have to take the water bottles of when i need to move the tubs. Oh and its by my bed and the rats make a lot of noise lol (yay poor college student) but thats not the racks fault. Anyways thanks for the post!
