Anyone wanting to be successful at the tropical fish hobby must put forth the time necessary to understand some basic fish tank water chemistry. This will help your fish to not only survive but thrive! I recommend that you get a good aquarium water testing kit or many individual kits. You will need kits that will test for the following:     * Ammonia     * Nitrite     * Nitrate     * pH     * Water Hardness     * Chlorine / Chloramine
