API® BIO-CHEM STARS biological media provides a home for growing massive colonies of nitrifying bacteria to establish and maintain a healthy aquatic ecosystem. The nitrifying bacteria convert harmful ammonia into nitrate. This is called the nitrogen cycle, and it occurs naturally in all underwater environments. Your fish will produce waste, which fuels the growth of the beneficial bacteria that will comprise your “biological filter”. These bacteria continue to grow as your aquarium ages – living on the top layers of the aquarium gravel, or in filter media such as API BIO-CHEM STARS biological media. Formed under a patented production process that creates a 50-70 micron internal pore network. This pore size is optimal for the growth of beneficial, nitrifying bacteria that remove toxic ammonia and nitrite. Space-age porous polymer allows for rapid transfer of oxygen and water which keeps bacterial colonies healthy and active. Due to their design, API BIO-CHEM STARS biological media achieve 4 times more surface area to colonize bacteria than ceramic rings. Size: 20pcs per pack. Rinse thoroughly to remove any dust. Place BIO-CHEM STARS biological media in the last compartment of your filter. BIO-CHEM STARS biological media will become colonized by bacteria within several weeks.

Rinse pouch under tap water to remove the loose dust. Pouch does not need to rinse clear. Place pouch in path of water flow in the aquarium filter.

Calcium is one of the most important elements in a reef aquarium. Reef invertebrates, such as corals, crustaceans, mollusks, 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. The API® CALCIUM TEST KIT measures calcium levels as low as 20 mg/L to help you keep your reef inhabitants healthy. Contains 2 test bottles, easy-to-ready instructions, and glass test tube.Best Before Guarantee: 28/04/2027

Copper – a treatment for many parasitic infections – must be monitored in an aquarium or a pond. The copper level can drop too low for the treatment to be effective, or can increase to a point that is detrimental to fish health. Copper is likely even present in your tap water. The API® COPPER TEST KIT allows you to easily and accurately monitor copper levels to maintain copper-based fish treatments at therapeutic levels, and tests copper levels from 0 to 4 ppm. The kit measures both free and chelated copper, and is for use in fresh and saltwater aquariums, or with ponds.
