Phosphate Is What Feeds the Algae

Nuisance algae and stalled coral growth usually trace back to phosphate. Reactor media strips it chemically, which is faster and more controllable than waiting for water changes to catch up — and running the media in a reactor rather than a bag keeps it tumbling so the whole volume stays active.

Match the Media to the Problem

Iron-based phosphate removers (GFO) — high capacity, the standard choice for reef systems and best run in a fluidised reactor.
Aluminium-based removers — an alternative chemistry, effective and often cheaper per litre.
Biopellets — solid carbon source that grows bacteria to export nitrate and phosphate together, run in a dedicated tumbling reactor.
Combined and specialty media — blended phosphate binders, magnesium media and coarse reactor substrates.

Bring phosphate down gradually. Stripping it fast can shock corals that have adapted to elevated levels, so start with a partial charge and increase. Questions? Email sales@jlaquatics.com.

J&L Aquatics was formed in December 1997

Our business was started from our love of the aquarium hobby. We at J&L Aquatics felt that the Canadian aquarist should have the option to purchase top quality supplies, equipment and livestock other than the generally over priced local retail stores.
