API has been an industry leader in fish care, nutrition, treatments, testing and pond products for over 50 years, giving them a keen insight into your aquarium and its needs - making them the clear choice for fish enthusiasts around the world.

API Marine Calcium offers a natural way to increase calcium levels in your reef aquarium. This product should be used whenever calcium deficiency is present in your water. Use API Marine Calcium when water tests show a calcium level below 400ppm mg L in your reef aquarium. Calcium is one of the most important elements in a reef aquarium. Reef invertebrates, such as corals, crustaceans, molluscs, and even some type of encrusting algae, need calcium to grow and remain healthy. Over time, the calcium level drops as it is used by invertebrates, or as it reacts with excess phosphate.

Key Features:

  • Marine Calcium for Saltwater Aquariums
  • Use whenever the water is Calcium deficient
  • Suitable for saltwater aquariums
  • Promotes the health of corals, crustaceans, molluscs, and algae

Feeding Guidelines

These are broad guidelines only, designed to assist with feeding your pet based on their weight, age and activity level. Always check the feeding charts on your pet's food packaging in conjunction with these feeding guidelines. Required amounts may differ between individual pets, and adjustments may be required to maintain optimal body weight.

Once or twice daily feeding is recommended for adult dogs, unless otherwise specified by your veterinarian. Puppies and kittens require feeding more regularly, with the total portion divided into three or four meals throughout the day. Ensure fresh water is available at all times.
