pH

pHpH is the most frequent cause of fish stress, which can ultimately lead to fish loss. Unfortunately, it is usually the most overlooked parameter. Fish cannot tolerate sudden changes in pH. Even a change of 0.2 can result in stress or death if it occurs suddenly.

Know the pH of your fish shop's water, as well as your own, so you can be acclimate new fish properly. Keep in mind that if you use tap water, it has dissolved gasses from being under pressure. Let it sit overnight before testing the pH.

pH can, and will, change with time. Fish and plant waste, water evaporation, water addition, and water hardness will all contribute to changes in the pH. As a rule of thumb, pH in an established tank should be tested once a month, and any time there is a fish death or illness.

Another factor of pH is the buffering capability of your water. If your water pH changes suddenly, or drifts regularly over time, you should check the KH (Carbonate Hardness) of the water. Consult your local fish shop for KH testing, and for buffering compounds to stabilize the pH level.
