Make sure it's type S true hydrated lime. I rinse water tank out good after Alum treatment but I treat 1/2 pond with Alum, then treat that part with hydrated lime, just pour the powder out the side of the boat. You can mix it pretty well in water if it's the right type of lime in powder form, I've not been exposed to any other courser type, never had an issue with agitation or keeping it suspended in a tank.. agitate and shoot, agitate and shoot.
