Brightwell NeoPhos - 500ML

Balanced Phosphorus Source for Phosphorus-Limited, Low-Nutrient Reef Aquaria

Overview
Used alongside MICROBACTER7 and REEF BIOFUEL or KATALYST, this product supports natural nitrogen uptake in systems where phosphorus is limited. It helps reduce ammonia, nitrite, and nitrate levels without chemical filtration media or adding excess organic material to artificially raise phosphorus. Available at Reef Supplies Canada and recommended for advanced reef aquarists running ultra-low nutrient systems. Reef Supplies Canada stocks it for reef keepers aiming for stable nutrient balance.

It can also be used with MICROBACTER7, REEF BIOFUEL, KATALYST, and NEONITRO to fine-tune nutrient levels for improved coral coloration and overall system health.

Technical Background
Low-nutrient and ultra-low-nutrient reef systems depend on a balanced supply of carbon, nitrogen, and phosphorus to support beneficial microbial activity. These microbes break down organic waste and convert it into biomass, which is then removed via protein skimming or consumed by corals and suspension feeders. This process helps recycle nutrients back into the reef ecosystem.

When any one nutrient is deficient, microbial processing slows and overall nutrient control becomes inefficient. Maintaining proper balance allows microbes to function effectively, helping prevent nutrient buildup and supporting zooxanthellae health in reef organisms.

Instructions and Guidelines
Shake well before use. Do not overdose. Best results occur when used with regular MICROBACTER7 dosing.

1. Test phosphate and nitrate levels using reliable test kits or calibrated digital testers. Phosphate is typically assumed to be below detection in ULNS setups.
2. Dose NEOPHOS as needed to reach approximately 0.02 ppm phosphate.
3. Wait 24 hours, then retest. If no change occurs, the system may be carbon-limited. Begin dosing REEF BIOFUEL at 1 ml per 25 US gallons and continue daily until nutrient reduction is observed.
4. If nitrate drops without carbon supplementation, phosphate will also decline. Continue dosing NEOPHOS to maintain ~0.01–0.02 ppm phosphate until nitrate stabilizes in the desired range (typically 3–5 ppm). Adjust as needed thereafter. Reef Supplies Canada recommends ongoing monitoring for stability.

Always refer to bottle instructions, as different strengths have been sold covering different system volumes.

Caution: Keep out of reach of children. Not for human consumption.
