Fluval C3 Bio-Screen Pad provides massive biological surface area for friendly bacteria to colonize, plus it blocks debris and evenly distributes water flow before it drips into the Power Filter's biological trickle chamber. Exclusively designed for the Fluval C3 Power Filter. 3-pack. Learn More

The Fluval G Fine Pre-Filter Cartridge is designed for daily use with marine aquariums where suspended debris is minimal or it can be used as a polishing cartridge for standard or fresh water aquariums. The fine mesh will trap debris 75? (micron) or larger for unparalleled mechanical filtering results. Designed as a no by-pass system, debris remains caught between each pleat until it is removed and rinsed. However, solid wastes can beak down into soluble wastes and regular cartridge rinsing is recommended. Learn More

Fluval Peat Granules are the all-natural way to soften aquarium water and achieve the pH levels required for breeding and rearing certain tropical fish. Peat contains humic acid, tanning agents, and trace elements that are essential for various life processes. Highly concentrated for maximum effectiveness, this product is recommended for fish that prefer soft, acidic water.

To ensure optimal conditions, it's best to test with Nutrafin pH and KH test kits on a regular basis to verify that desired levels are being maintained. A KH range of 50-120 mg/L (approximately 3-7 dKH) is usually recommended for fish that thrive in soft, acidic water. Use Nutrafin pH Stabilizer for superior results in maintaining an optimal KH value. Learn More

• This is a case of 24 packs, each containing 3 nylon bags of 100g Carbon for a total of 72 bags.
• Fluval carbon is very pure activated carbon that is ideal in both Fresh and Salt water. The inner matrix structure provides a large porous area that permanently traps organic waste while removing liquid wastes such as urine, dyes or many other impurities from the water. The result is sparkling clear aquarium water.
• Fluval Carbon premium, research grade, low-ash carbon improves water clarity and color, while also removing odors. Highly porous, it provides large amounts of surface area for adsorption of impurities. It effectively removes heavy metals, odors, discolorations, organic contaminants, and pollutants to leave your aquarium water crystal clear and sparkling. This product does not release phosphates. Carbon loses its activity without outward sign. Replace monthly to ensure that active absorption is maintained.
• Carbon should always be removed when medication is being administered in aquarium water. Also, because carbon will adsorb a large percentage of the nutrients in plant fertilizer products, it should be used carefully when keeping live plants. For freshwater and marine environments.
• Premium select media for use in Fluval Canister Filters, ideal for all filters. Learn More
