Brightwell Aquatics NeoPhos
Overview
- Used in conjunction with MICROBACTER7 and REEF BIOFUEL or KATALYST, enables natural nitrogen uptake to take place in systems with inadequate phosphorus content, lowering ammonia, nitrite, and nitrate concentrations without the use of chemical filtration media and without resorting to polluting the system with organic material to raise the phosphorus content.
- Recommended for use by advanced reef aquarists maintaining ultra-low nutrient content systems, only.
- May be used with MICROBACTER7, REEF BIOFUEL and/or KATALYST, and NEONITRO to achieve desired nutrient content in reef aquaria for improved health and coloration of inhabitants.
Technical Background
Successfully-operated low-nutrient and ultra-low nutrient systems rely on precise nutrient balance. NeoPhos supports natural phosphorus cycling, allowing beneficial bacteria to efficiently process nitrogen waste. This helps maintain stable water parameters without introducing organic pollutants or chemical additives.

Michael Fraser –
After using NeoPhos with MICROBACTER7, my reef tank showed better water stability. Ammonia and nitrate levels dropped significantly over three weeks. The system remains clean without needing frequent water changes. Highly effective for low-nutrient setups.
Sonia Abraham –
Works well when combined with REEF BIOFUEL. I noticed improved coloration in my corals after a month. No visible side effects or cloudiness in the water. Still requires careful monitoring of nutrient levels.
Brian Dowd –
As an advanced reef keeper, I rely on NeoPhos to maintain ultra-low nutrient conditions. It’s a reliable supplement that supports natural nitrogen cycling without adding organic waste.
