A stable pH is critical to a healthy aquarium.Alkalinity is a measure of the compounds that stabilize pH.Hardness is principally a measure of the calcium and magnesium in your water. If water conditions are not within the desired range, your fish may become stressed and susceptible to disease. Note: When fish species from different locations are kept, a tank is referred to a community tank and a general range of conditions are recommended.Ammonia is produced by fish as waste and as a result of the breakdown of uneaten food and is toxic to fish even at low levels.Nitrite and Nitrate are byproducts of the nitrogen cycle, a natural process that breaks down waste in aquariums. Nitrite is more toxic than nitrate, and should be held below 1 ppm.Mardel Test Strips use the same technology found in medical laboratories and replace other potentially toxic and time-consuming kits. They are designed to be accurate and dependable while being safe and easy-to-use.
