The Bulk Bio Pellets Nitrate Reducer is a high-quality solution for reducing nitrates and phosphates in saltwater aquariums, which helps to prevent algae growth. These pellets are made from pure PHA biodegradable plastic resin, ensuring they break down naturally over time without harming the environment or your tank inhabitants. As the pellets degrade, they release carbon that promotes the growth of beneficial bacteria capable of converting harmful nitrates and ammonia into nitrogen gas and proteins. This process effectively reduces nitrate levels and contributes to a healthier aquarium ecosystem. Ideal for use in fluidized bed reactors, these bio-pellets are best used by experienced aquarists looking to fine-tune water quality parameters and maintain pristine conditions in their reef tanks.
