Proper pH control is imperative to prevent the harmful effects of too alkaline or too acidic pond water on fish and plant life.
The pH range of 6 to 8.5 is acceptable for most pond life. The primary concern with pH is its direct relationship to the toxicity of ammonia and nitrite. Each pH interger above the neutral 7 reflects a tenfold increase in such toxicities.
Any pH value below the neutral 7 is considered acidic. Baking soda or ground limestone will raise the pH level.
When choosing a new pump, it is important to look at all factors. Obviously, we first want to make sure the pump will provide the desired flow. Then we look at purchase price, and warranty. An often overlooked factor is the cost of operating the pump.
