Brightwell Aquatics Phosphat-E is a highly concentrated liquid phosphate remover that eliminates reactive phosphate (PO4) as soon as it is added. It is the quick, precise way to knock back the phosphate that fuels hair algae, cyano and dinoflagellates and holds back coral growth and colour.
Key benefits
- Works immediately – binds reactive phosphate on contact; the precipitate is removed by your skimmer and mechanical filtration.
- Precise & powerful – 1 ml removes 1 ppm of phosphate in 4 US gal (approx. 15 L); rated over 50% stronger than competing products.
- Reef safe – safe for fish, corals and invertebrates when dosed as directed.
- Ideal for ongoing phosphate control in heavily stocked or heavily fed tanks.
How to use
- Test phosphate first so you know how much to remove.
- Basic: up to 5 ml per 20 US gal (approx. 76 L) per day for every 1 ppm of phosphate present.
- Maximum: never exceed 1 ml per 4 US gal (15 L) per day.
- Add slowly near the skimmer intake or mechanical filter. Lower phosphate gradually over several days rather than all at once.
Good to know
- Temporary cloudiness is normal and clears as the skimmer and filter socks remove the precipitate.
- Harmful if swallowed; avoid eye and skin contact. Keep out of reach of children.
