I recently purchased a 50lb bag of A.R.M. and noticed that it contained countless yellow granules mixed throughout the media which I have never encountered before when buying the individual 8lb containers. Anyone know what these granules are and if they would harm the the tank (mostly acropora sp.) if used? FWIW the granules are "chalk-like" and readily crumble when crushed. TIA!
