Nyos Nitrate Minus is a high purity biological supplement designed to effectively reduce nitrate levels in marine and freshwater aquariums. Acting as an organic carbon source, it fuels the growth of specialized bacteria that consume excess nutrients, helping maintain a healthy and balanced environment for your fish and corals. This innovative solution allows aquarists to achieve near detection limit water purity without compromising the safety of sensitive reef inhabitants.

The formula features a unique dual action blend consisting of short term and long term active components to provide immediate nitrate reduction while establishing a stable bacterial population over time. Unlike many other carbon sources on the market, this product contains no toxic methanol making it safer for your livestock. It also facilitates a secondary reduction in phosphate levels as the resulting bacterial films are efficiently removed from the water column by your protein skimmer.

This supplement is best suited for reef keepers looking to maintain nitrate levels within the ideal range of 5 to 15 mg/l or those needing to bring spiking values back under control. By keeping nitrates stable, you prevent the growth of nuisance algae and promote better coral coloration and growth rates. Whether used as a permanent maintenance solution or a temporary treatment, it enhances overall system health and supports long term aquarium stability.
