Blane, unless you already have, please do not put table shrimp in your tank. Your tank is cycled. LIVE ROCK OR LIVE SAND instantly cycles a tank, as evidenced by your zero ammonia and nitrite. Anytime you add a fish the tank takes a short time to accomodate the new load, that's why adding slowly is important. This is no different for your tank than it is a six month old tank. Don't waste your time by RE-cycling your tank with a decaying ball of dead animal. Continuing your current water change schedule is a good safeguard IN CASE OF a spike, which is VERY UNLIKELY unless you add 10 fish at once. Add ONE fish, make sure it does fine for a week, keep testing parameters, and go from there...
