So I tried the Oil-Dri and whether it was old stock or what, it crumbled in less than a season. So I figure "why fight it, I'll buy the Turface." I know it can't be bad. I know the MVP is the right particle size. But the place that said they could get it is "closed" for now. My farm and home store checked and just told me they can get Pro's Choice and "it's the same thing." Knowing how dangerous of a statement that is, does anyone have experience with this brand. I am sure it will be more durable than the DE I tried but I'm concerned about particle size. I will read up their site but was hoping someone could make a suggestion so I can call them back and get it ordered. I'd really hate to get the wrong size and waste time/money and still not have a suitable product.
