The pH value indicates how acidic or alkaline your aquarium or pond water is. A doubling of the pH-value means a doubling of the bases (the opposite of acids) in the water. That’s why regular checks are important! Here we’ll show you the right way to carry out the water test. Ranging extensively from pH 3.0 to 10, this test gives us an idea of where we are in the pH range.
