Most breeders suggest 6 quart for hatchlings up to around 200 - 300 grams, 15 quart from 200 - 500 grams, 32 quart from 500 - 1500, and 41 quart from 1500 grams up. There are some breeders, on the other hand, that use 28 quart from 200 grams up. IMO, do what works best for you. I don't think that it matters what type of plastic tub you use. Try to find tubs that are smooth, because they will be easier to clean than tubs that are not smooth.

Good luck.
