Brightwell Aquatics NeoPhos Balanced Phosphorus Supplement

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 Instruments 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
