Brightwell Aquatics NēoPhos Phosphate Reef Supplement, 500 ml

Use this phosphate reef supplement in low-nutrient reef aquariums where a phosphorus source is called for. The bottle holds 500 mL of liquid and is dosed to raise phosphate by roughly 0.02 ppm, then the water is retested after 24 hours. It is intended for advanced reef aquarists running ultra-low nutrient content systems (ULNS).

How the dosing works

Shake the bottle well before use, then test phosphate and nitrate levels in the tank. Apply NeoPhos for approximately 0.02 ppm, wait 24 hours and retest. If the levels persist, keep going until carbon, phosphorus or nitrogen come into balance, and repeat the process until you reach the result you want.

Microbacter7 is dosed daily or every two days alongside this routine. NeoPhos is designed to be used with Microbacter7, Reef Biofuel and Katalyst.

What the supplement does in the tank

NeoPhos supplies phosphorus for low-nutrient reef aquariums. The formula regulates organic carbon, nitrogen and phosphorus, and it balances carbon, nitrogen and phosphorus in the aquarium.

The 500 mL bottle is liquid, and the manufacturer sets the product apart for advanced reef aquarists who keep ultra-low nutrient content systems. That audience is part of the product's stated design, not a limit on tank size.

Who this supplement suits

This product is meant for experienced reef keepers who run systems with extremely low nutrient levels. It is a phosphorus source, so it belongs in a tank where phosphate is being held low on purpose, and it is dosed for about 0.02 ppm at a time followed by a 24-hour wait and a retest.

Check that you have a phosphate and a nitrate test on hand before starting, and that you keep Microbacter7, Reef Biofuel and Katalyst in your routine, since the product is designed for use with them.
