Water quality is a major part of keeping your aquarium running smoothly. Weather it's freshwater, saltwater, pond, or a turtle tank, we can provide you with a complete water test to help fix or avoid any problems that you may be having. We provide water testing for free. When bringing water to be tested, bring about 2 ounces in a clean contain or bag. The water sample should be as fresh as possible leaving it in the sun or overnight in the cold could contaminate the sample.
