Testing for General Hardness (GH) should be done to determine if the levels of Calcium (Ca) and Magnesium (Mg) are optimal for specific species of fish. Carbonate Hardness (KH) levels need to be tested on a regular basis because they fluctuate over time and can negatively impact the pH balance of the aquarium water. Low Carbonate Hardness will result in poor plant growth. Suitable for fresh and salt water.
Decorative aquarium gravel is the ideal way to enhance the appearance of you fish tank. Made from silica aggregates known for their inert properties and coated in a colourfast resin for trouble free fish keeping, this gravel is suitable for all types of aquarium set-ups including coldwater, tropical and saltwater, and is also the perfect planting medium due to its finer size. Suitable for bottom feeders and barbed fish, it will not change the PH of the water.
Marine aquariums rely on beneficial bacteria living in the filter, substrate, and rocks to remove the harmful ammonia that fish produce. In their absence, levels would rise quickly and prove fatal to most aquarium inhabitants. These bacteria take time to develop, and traditionally in new aquariums the addition of fish has to be done slowly to prevent sudden increases in dangerous waste products. Tetra Marine SafeStart adds the correct mix of marine bacteria to the aquarium, to speed up their development, allowing the safe introduction of fish. With SafeStart, ammonia levels are reduced, and the aquarium can be stocked in less time.
