media ther is a movement in the aqua-world to cycle tanks without fish. As it can be very deadly to the fish you use, even if they survive they sometimes have ill effects. Alot of people feel that is cruel to the fish and is the cause of many dead fish every year. I'm not saying I agree or disagree, it is just a choose each of us need to choice for ourselves.

As far as how much put in a cap full every other day and take readings once a day until the you have a spike in nitrates and then falls to zero.....
