Testing your water parameters is a must for any aquarium hobbyist. If water quality is neglected the results could be terrible, disease could run rampant in your aquarium and your fish could even die. To avoid these terrible consequences test your water on a regular basis. We’d recommend you test for the big three Ammonia, Nitrate and Nitrite daily when starting your aquarium and going through the cycling process. However once your aquarium is mature and has settled in you can test once or twice a month just stay on top of your water changes.
