There’s not much to say about the actual product itself as it’s just monosodium phosphate I add as the CA:P ratio is poor in my hay. That being said, it used to be little crystals that were easy to handle, scoop and weigh. A while ago the product changed to a white powder that has huge clumps all throughout it. It’s very annoying to have to break it down prior to weighing it and adding it to my horse’s supplements. I’ve addressed this with Madbarn and they hope to go back to the granules eventually.
