Key Features Helps to prevent algae growth Can be used in both ponds and aquariums 3 in 1 treatment - contains 25 test strips Measures Phosphate, Nitrates, and Carbonate Hardness Fast and easy testing Tetra Test AlgaeControl 3-in-1 is the optimal aid for preventing algae growth in ponds and aquariums. It is important to test your pond or aquarium water regularly to ensure stable KH values and to check for other harmful chemicals. With the Test AlgaeControl 3-in-1 you can measure water values such as nitrate (NO 3), phosphate (PO 4), and carbonate hardness (KH). The 25 included test strips makes it easy for you to control the most important algae parameters in your water. Included: 25 test strips What does it measure? Carbonate hardness (KH) - Represents the hydrogen carbonate concentration which acts as a PH- buffer A stable buffer capacity will be achieved by KH values >= 6°dH. It’s very important for stable water values to prevent a sudden drop in acid content. Treatments are
