Kolar Labs HC GFO Phosphate Remover 700g (1.54lbs)

Product details

Kolar Labs HC GFO Phosphate Remover 700g (1.54lbs) is a phosphate-removing filter media made from granular ferric oxide (GFO). It’s designed for use in aquarium filtration to help reduce phosphate levels—the nutrient that can feed algae. By binding phosphate as water passes through the media, it supports clearer water and a healthier aquarium environment, particularly in systems where algae control is a priority. Use it in appropriate filtration setups such as reactors or filter media compartments, depending on your tank’s flow and equipment.

Features:

• Rapidly eliminates phosphates on contact to reduce an algae food source
• Helps remove certain additional contaminants, including silicates, arsenic, and many heavy metals
• Reduces and helps prevent stubborn algae growth by lowering phosphate
• High-capacity “HC” media is intended for longer-lasting phosphate removal compared with standard GFO media
• Low fines and dust for cleaner handling and more consistent filtration use
• High hardness and density material helps resist abrasion, supporting reactor-style usage
• Works in fresh and saltwater aquariums, including reef tanks and high-end marine fish tanks
• Can be used in reactors, filter socks, canister filters, and filter cartridges
