FERRIX-03 High-Capacity GFO | Phosphate, Silicate & Heavy Metal Remover
FERRIX03
Why the 03?
Three Targets. One Media.
The 03 represents the three contaminant classes FERRIX strips from your water — each one a known driver of livestock stress, nuisance algae and system degradation.
Phosphate fuels algae and suppresses coral calcification. Silicate drives brown diatom films. Heavy metals accumulate in fish tissue and invertebrates over time. FERRIX-03 locks all three onto its granule surface — permanently — until you swap the media out.
The Algae Fuel
The number one driver of nuisance algae, cyanobacteria blooms and suppressed coral calcification. FERRIX-03 locks phosphate onto the media surface — permanently — until you change the media out.
The Diatom Fuel
Silicate drives the brown diatom films that plague reef and freshwater systems alike — and it's on FERRIX-03's proven removal list, not hidden in the fine print like most budget GFO.
The Silent Accumulators
Tap water top-ups, salt mixes and fish food all drip-feed metals into your system. FERRIX-03 strips arsenic, copper, lead, zinc and more before they accumulate in livestock tissue.
What FERRIX-03 Removes
Every contaminant below is adsorbed by FERRIX-03 as water passes over the granules. No guesswork — just clean water.
- ~300 m²/g reactive surface — physisorption and chemisorption across the full granule
- 60% iron content — more active sites per gram than standard aquarium GFO
- 0.2–2.0 mm low-dust granule — rinses clear fast, won't cloud your system
- Professional-grade purity — compatible with reef, freshwater, RAS and pond filtration
Where FERRIX-03 Works
🐠 Reef & Marine
Strip phosphate and silicate to starve nuisance algae, protect coralline encrustation, and support hard coral calcification. Low-dust granules rinse clean — no clouding your display.
🌿 Freshwater & Planted
Kills diatom films and heavy metal accumulation without stripping beneficial trace elements that plants actually need. Ideal for tap-water top-ups where copper and lead creep in.
🏭 Aquaculture & RAS
High-capacity adsorption for recirculating systems where phosphate and metals accumulate across thousands of litres. Longer media life = less downtime = lower operating cost.
💧 Ponds & Outdoor
Tackle phosphate spikes from leaf litter, fish waste and runoff. FERRIX-03 binds phosphate permanently on the granule surface — it can't leach back into your water.
How FERRIX-03 Works
Rinse First
Place FERRIX-03 in a fine media bag or filter sock and rinse under tap water until it runs clear. The low-dust granule cleans fast — usually under a minute.
Fluidised Reactor or Media Bag
Run it in a phosphate reactor for maximum contact, or drop the media bag into a high-flow area of your sump. More flow = more contact = more removal.
Test & Monitor
Check phosphate levels with a reliable Hanna Checker or equivalent. When PO₄ stops dropping, media is exhausted — swap it out.
Change & Repeat
Fresh media in, old media out. Don't try to regenerate it — once GFO is saturated, it's done. Buy once, cry once.
