Brightwell Aquatics NeoPhos is a liquid phosphorus supplement for reef aquariums where phosphate has been stripped to zero. Bottomed-out phosphate is a common cause of pale or bleaching corals, tissue loss, stalled growth and dinoflagellate outbreaks in “too clean” tanks. NeoPhos lets you bring phosphate back up to a small, stable, measurable level.
Key benefits
- Fixes zero-phosphate problems – helps restore coral colour, growth and zooxanthellae health.
- Balances nutrients – target approx. 0.01–0.02 ppm phosphate with 3–5 ppm nitrate.
- Pure – purified water and phosphorus salts only.
- Designed to work with Brightwell NeoNitro, MicroBacter7 and Reef BioFuel.
How to use
- Shake well and test phosphate with an accurate low-range test.
- Dose according to the strength printed on the bottle label to reach about 0.02 ppm, then retest after 24 hours.
- If phosphate does not rise as expected, the system may be carbon-limited – add Brightwell Reef BioFuel (1 ml per 25 US gal / 95 L) and retest.
- Do not overdose – small, regular additions are best.
