How to Decrease Water PH Naturally

When measuring the quality of aquarium water, one of the most important aspects is its pH, which measures its acidity and alkalinity. Most freshwater fish require a pH of 7.0, or neutral, for a healthy environment, but there are many cases where the pH may need to be lowered to better emulate the natural habitats of your tank's inhabitants. In fact, most fish that come from the Amazon, like knife fish or discus, prefer a pH level of 6.0 to 6.5. Fortunately, there's a method of lowering pH naturally without the use of potentially harmful chemicals, and this method also enhances the natural beauty of your aquarium.
