API® BIO-CHEM STARS biological media offers an ideal environment for cultivating extensive colonies of nitrifying bacteria, essential for creating and sustaining a vibrant aquatic ecosystem. These beneficial bacteria play a crucial role in transforming harmful ammonia into nitrate, a process known as the nitrogen cycle, which happens naturally in all aquatic habitats. As your fish produce waste, it supports the flourishing of these helpful bacteria, forming what is referred to as your “biological filter.” Over time, these bacteria will thrive, establishing themselves in the upper layers of your aquarium gravel or within filter media like API BIO-CHEM STARS. This media is crafted using a patented process that generates a network of internal pores measuring 50-70 microns. This specific pore size is ideal for nurturing beneficial nitrifying bacteria that effectively eliminate toxic ammonia and nitrite. The advanced porous polymer design facilitates swift oxygen and water flow, ensuring the bacterial colonies remain robust and lively. Thanks to this innovative design, API BIO-CHEM STARS biological media provides four times the surface area for bacteria colonization compared to traditional ceramic rings. Quantity: 20 pieces per pack. Be sure to rinse thoroughly to eliminate any dust. Position BIO-CHEM STARS biological media in the final compartment of your filter. Within a few weeks, BIO-CHEM STARS biological media will become populated with bacteria.

Featuring an exceptional combination of resins and activated carbon, API® BIO-CHEM ZORB filtration media effectively eliminates aquarium contaminants – such as colors, odors, heavy metals, and harmful gases – ensuring your aquarium water remains crystal clear. This product also filters out light-blocking impurities, promoting healthier growth for corals in saltwater aquariums and enhancing plant vitality in freshwater setups. 1 pack - size 6. Rinse the pouch under running water to eliminate any loose dust. The pouch does not need to be rinsed until completely clear. Position the pouch in the water flow area of the aquarium filter. Replace every 2 months, or sooner if the aquarium is heavily stocked and/or if colors or odors become noticeable.

CupriSorb is an exceptional adsorbent specifically designed to capture copper and heavy metals. It outperforms carbon in the swift and efficient removal of copper, making it an excellent choice for urgent copper elimination. CupriSorb effectively extracts all forms of copper, including chelated varieties, maintaining its potency until it changes to a deep blue-black hue. It can be regenerated multiple times. When used continuously, it will gradually remove even precipitated copper from the gravel or substrate bed. CupriSorb enables the care of invertebrates in tanks that have been treated with copper by eliminating the copper leaching from substrates. CupriSorb is a robust chelating resin that specifically targets copper. Unlike competing options, which are simply cation exchange resins, CupriSorb is effective in both freshwater and saltwater environments, while others may only work in freshwater. FEATURES: Highly effective adsorbent for copper and heavy metals Copper-specific chelating resin Removes all forms of copper DIRECTIONS: For every 600 L (150 US gallons), use 250 mL to eliminate up to 7,500 mg (12 ppm) of copper. Place it in a filter media bag, such as The Bag. To achieve optimal results, position CupriSorb to enhance water flow through it. To effectively address undetectable copper leaching from substrates, keep CupriSorb in use for a minimum of 2 weeks after copper tests indicate no copper presence. It can be utilized in a canister filter, chemical filtration module, box filter, or any area with high flow in a trickle filter.
