## Description

NeoPhos - Balanced Phosphorus Source for Phosphorus-Limited, Low-Nutrient Reef Aquaria - Aquarium Water Treatments, 67.6 fl oz

## 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. Made in the USA, we consistently deliver advanced superior quality solutions to elevate the vibrancy and health of your aquarium

## Questions & Answers

**Q: Can I use this for freshwater plants?**
A: Yes, it is a phosphorous supplement and is similar to our Florin P.  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.
