We ordered some 3000 gal vertical (poly) tanks to take delivery of 32% and store until planting time. I want to put them on an existing cement slab (ex pig barn), which is sloped (maybe 6" over 10'). How much slope can these tanks tolerate before it is a risk of tank failure? The tanks are about 10' tall, so it would be leaning.
