NeoPhos BrightWell Aquatics

Brightwell Aquatics NeoPhos is a concentrated phosphate supplement used to increase phosphate (PO₄) levels in marine and freshwater aquariums. It’s commonly used in reef tanks where phosphate has become too low due to aggressive filtration, media, or heavy nutrient export.

Key benefits:

• Raises phosphate safely and predictably.

• Helps prevent nutrient starvation in corals.

• Can improve coral coloration, growth, and polyp extension when phosphate is deficient.

• Supports healthy zooxanthellae and overall coral metabolism.

• Free of unnecessary organic additives.

When to use:

• Your phosphate consistently tests at 0.00 ppm or below your target range.

• Corals appear pale, have poor growth, or show signs of nutrient deficiency.

• You’re using phosphate-removing media or dosing carbon that has driven phosphate too low.

Target phosphate for most reef aquariums:

• SPS-dominant reefs: 0.03–0.08 ppm

• Mixed reefs: 0.03–0.10 ppm

• LPS/soft coral reefs: 0.05–0.10 ppm (sometimes slightly higher is acceptable)

Important:

• Raise phosphate gradually and test frequently with a reliable checker, such as a Hanna ULR Phosphorus Checker.

• Avoid increasing phosphate too quickly, as sudden changes can stress corals and encourage algae growth.

• If nitrate is also very low, balancing both nutrients (rather than only increasing phosphate) often produces the best coral health and coloration.
