A question about fish tank cycling?

You can easily buy something called prime from a local fish store that will do the job. Or you can let the tank be idle meaning, let the filter fun and whatever else without fish for a few days and that should be fine. Fish should not be added until after the cycling of the water in the tank because the fish may not be able to survive due to the chemicals and lack of oxygen of the water. The best is just getting prime, look it up on petco or petsmarts website. They should also have it at walmart. The bottle seems expensive but you only use a few drops so it lasts a good about of time. I have been using it for a while it helps with purifying the water as well as the slime coat of your fish so it keeps them healthy.
