I have a Bac Pac, a water filter, aragonite substrate, and two very large pieces of live rock. My aquarium is 29 gallons. I also got some bio-balls from an established aquarium. I have 3 blue damsels. How long till my tank cycles? How many fish or how many inches of fish can I have per gallon? It has been set up for two weeks. How will I know when I can add more fish? Am I missing anything? No one has died and no one looks distressed, everyone is active and eating well.
