Maintaining a thriving ultra-low-nutrient reef aquarium requires a delicate balance of carbon, nitrogen, and phosphorus. NeoPhos is specially formulated to provide the essential nutrients necessary for beneficial microbes to efficiently remove latent organic material, promoting a healthy ecosystem for your zooxanthellate invertebrates. NeoPhos ensures a precise balance of carbon, nitrogen, and phosphorus, supporting microbial activity crucial for the removal of organic waste and fostering a perpetual supply of planktonic microbes. The carefully calibrated formula supports microbial uptake of nutrients, preventing the accumulation of waste and promoting the well-being of your reef system. NeoPhos is vital for the existence of zooxanthellae and zooxanthellate invertebrates, aiding in the prevention of bleaching and tissue degradation. Whether you're setting up a new tank or maintaining an established one, choose NeoPhos for a meticulously crafted solution that supports the delicate balance required for the health and longevity of your reef aquarium.

Do not overdose. Results will be most significant when the system is being dosed with MicroBacter7 on a daily or bi-daily basis. 1. Using accurate test kits or calibrated digital testing devices, determine phosphate and nitrate concentrations in system. It is assumed that the phosphate concentration in the system is below detectable limits for the testing method being employed. 2. Apply NeoPhos as directed below to attain a phosphate concentration of ~0.02 ppm. 3. Allow 24-hours to elapse; re-test nitrate and phosphate concentrations. If concentrations remain unchanged, then the system is likely carbon-limited. Dose with Reef BioFuel at the rate of 1-ml per 25 US-gallons and allow 24-hours to elapse, then re-test phosphate and nitrate concentrations. Continue daily dosing with Reef BioFuel until phosphate or nitrate concentrations begin to decrease, indicating that the rate of carbon input to the system matches the rate of phosphorus- or nitrogen-input, respectively. 4. If nitrate concentration decreases without addition of Reef BioFuel or use of Katalyst, phosphate concentration in the system will decrease. Continue dosing with NeoPhos to maintain phosphate concentration of ~0.01 - 0.02 ppm until nitrate concentration falls to within desired range (suggested 3 - 5 ppm). Thereafter, dose with NeoPhos as required to maintain desired phosphate and nitrate concentrations. Note: If at any time, dosing with NeoPhos results in a prolonged increase of phosphate concentration without gradual decrease as nitrate is taken up, system is likely carbon-limited (remedied by the application of Reef BioFuel or Katalyst to the system). Refer to Steps 3 and 4, or to our website (NeoPhos "Technical" page). 1 ml NeoPhos will increase the phosphate concentration in 1 US-gallon (~3.8 L) by ~1.2 ppm; 1 drop from plastic bulb pipette (enclosed within bottle) will increase the concentration in the same volume of water by ~0.06 ppm. Caution: Keep out of reach of children. Not for human consumption. Review: Brightwell makes amazing products, but the packaging needs improvement. I’m a frequent customer and have purchased several times on desertcart products I can’t find at my local fish store (LFS). However, I’ve noticed that delivery through desertcart often causes issues with the packaging: the container’s seal is fragile and can break with the slightest impact. In addition, the screw-on lid does not fully secure the contents, making it easy for the product to spill. Unfortunately, today I woke up to find 2 liters of NEOPHOS spilled all over my living room floor. It’s frustrating to lose such a high-quality product due to a packaging flaw. Brightwell should consider a more durable packaging design to prevent these kinds of incidents. Review: This product as with most Brightwell products is very diluted. It works good for newer reefs, but falls short once your corals start really growing. I am currently dosing 60ml a day of this product and having a hard time keeping my P04 up. I will probably just start making my own solution using Loudwolf sodium phosphate. ## Features - NATURAL NITROGEN UPTAKE – NeoPhos is a phosphorus source for low-nutrient reef aquariums. It supports beneficial microbe activity by regulating organic carbon, nitrogen, and phosphorus. Without one of these, microbial uptake slows, leading to increased concentrations of remaining nutrients - BALANCES NITROGEN – It's designed to work alongside other products like Microbacter7, Reef Biofuel, and Katalyst in reef aquaria systems. This nitrate regulator for fish tanks specifically caters to advanced reef aquarists maintaining ultra-low nutrient content systems (ULNS) - FOR ADVANCED REEF CARE – NeoPhos helps balance carbon, nitrogen, and phosphorus in aquariums. Microbes transform waste into microbial biomass, consumed by corals or invertebrates, recycling organic matter and providing live planktonic food - DIRECTIONS – Shake well before use. Dose Microbacter7 daily or bi-daily. Test phosphate and nitrate levels. Apply NeoPhos for ~0.02 ppm. Wait 24 hours, retest. If levels persist, continue until carbon, phosphorus, or nitrogen balances. Repeat process for desired result - AMERICAN-MADE EXCELLENCE – Brightwell Aquatics is an industry-leading brand committed to providing innovative and scientifically backed aquatic care products.

Please fill out the webform on the Brightwell site and we will try to help you with dosing. We will need to know something about the plants you are keeping and the size of your aquarium. **Q: Does this increase phosphate levels?** A: Yes, that’s exactly what this is for. They include the calculation on the back to determine exactly how much to dose to reach your desired levels. Great product. **Q: Do you have to use this in conjunction with the NeoNitrate additiive that they also make?** A: It is not required. If you are just phosphate deficient just add the neophos if your ok with the nitrate. However, if you are also nitrate deficient then yes you can use together. But you don’t have to use them together if you don’t need to. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***O on 15 August 2025* Brightwell makes amazing products, but the packaging needs improvement.
