run a filter with floss or similar for mechanical filtration, it will clearup nicely in a few hours. it is dirty, but remember, it was not made for aquariums but to soakup fluids or spread on turf like gravel. it does drop ph initially but that effect goes away eventually. if the kh/ph difference is going to be that great, i think you will have to do a gradual change or soak it in a big bucket for a week or so, changing water daily. this will help with its other property of being very light initially, until it soaks up water. good luck, i am using this on all my non-scaped (but still planted) tanks for inverts and such and love it. though for scaped, heavy planted tanks, i still prefer ADA aquasoil. you cant beat the price for oil-dry.
