EHEIM phosphate outThis powerful phosphate remover effectively curbs algae proliferation.EHEIM phosphateout features a unique iron formula designed for chemical filtration. The iron attaches to phosphate particles, extracting them from the water system and gradually lowering the phosphate levels in your aquarium. This action primarily helps to prevent algae growth.When phosphate levels rise again, indicating increased algae development, it’s time to replace the exhausted filter medium.EHEIM phosphateout comes in granulated form for external filters and as a foam cartridge for internal filters. It is devoid of harmful substances and suitable for both freshwater and saltwater environments.Phosphate remover prevents algae growthIron-based, free from pollutantsCompatible with fresh and saltwaterSingle-use (replace when phosphate levels rise again)Available as granules for external filters or foam cartridges for internal filtersChemical filter mediaDepending on their type, chemical filter media can affect pH levels and water hardness (like peat) or lower phosphate levels and suppress algae growth (as with phosphateout).Typically, tap water has a pH level ranging from 7.3 to 7.8, making it slightly alkaline. However, most ornamental fish thrive in more acidic conditions—ideally, a pH below 7.0. EHEIM PEAT pellets help decrease pH levels and soften water hardness.Phosphates primarily arise from organic debris in aquarium water (such as leftover food and waste) and are a key contributor to algae growth. EHEIM phosphateout captures these phosphates and removes them from the water cycle.

Utilizing leaching effectively can enhance the planting of NITROBAERIA. Avoid backflow as it negatively impacts the leaching process. Instead, maintain a consistent water level to boost the antiviral properties of the water, while also increasing its oxygen content. This can greatly improve filtration efficiency. The Ceramic Ring provides ample space for beneficial bacteria to flourish, which aids in the natural elimination of toxins from your aquarium. It plays a crucial role in the nitrification process, ensuring that your fish remain healthy and comfortable, while keeping the aquarium visually appealing. Ideal for both fresh and saltwater fish tanks. Maximizes the biological filtration capacity of low porous filter rings. This product is a blend of soft active carbon and ceramic materials. Chemically stable and fully compatible with the natural chemical environment of living microorganisms. High permeability facilitates both aerobic nitrification and anaerobic denitrification, resulting in more stable water—making it the best choice for biological filtration material.

Bio Filtration Bioball 37mm EXCEPTIONAL FILTRATION! Each bio ball features spines that significantly enhance the surface area to nearly 2 square feet, allowing for a vast number of beneficial bacteria to thrive. These helpful bacteria effectively break down harmful organic waste. You will receive about 300 bio balls, each measuring 1-1/2 inches, conveniently packaged in a mesh bag. Simply rinse and they are ready for use. STURDY AND DISTINCTIVE! The spherical design and strategic spine arrangement of our bio balls enable them to fit snugly into any shape or type of filter while maximizing surface area. Crafted from high-density plastic, these balls are lightweight yet robust enough to maintain their form, ensuring they will not degrade or wear over time. Bio balls can be utilized loose or within the mesh bag equipped with a plastic zipper. RELIABLE! Our Bio balls are comprised of 100% polypropylene, making them a dependable choice for biological filtration in both freshwater and saltwater environments. They are designed for use in koi and water garden ponds, freshwater aquariums, saltwater tanks, aquaponics systems, fish hatcheries, and much more. SUPERIOR TO LAVA ROCK: Over time, porous lava rock can become clogged with debris, reducing its surface area and its capacity to support beneficial bacteria. In contrast, the uniquely positioned spines of our bio balls allow most debris to flow through them easily. While lava rock has tiny pores that make cleaning a challenge, bio balls typically do not require cleaning in most applications. Additionally, a bag of wet lava rock can be significantly heavier than our bio balls. EASY TO CLEAN - When organic waste accumulates in the bioballs, they can be gently rinsed in dechlorinated water to eliminate debris and rejuvenate the bioballs. To capture larger particles before they reach the bioballs, use our FilterFIrst dual density bonded filter pad or water polishing pad.
