AF130 Media Reactor 5000 ml — Fluidised Filter for Large SPS Reefs GFO Zeolite - Aquaforest

Aquaforest AF130 — fluidized media reactor 5,000 ml for large SPS tanks and GFO

The AF130 Media Reactor is the large-reef format in Aquaforest's fluidized lineup, sized for 400-700 L tanks with sustained consumption. Useful volume 5,000 ml — nearly double the AF110 — that loads large volumes of activated carbon, GFO, biopellets, or zeolite without frequent reloads. Clear acrylic column to watch fluidization, internal baffles tuned to circulate media across the whole column height.

Format aimed at established aquarists managing large reef systems or who want to maximize per-media efficiency without multiplying smaller reactors.

Typical AF130 applications

• Large activated carbon — 2-4 kg of Aquaforest carbon or equivalent for 400-700 L tanks.
• Bulk GFO — phosphate removal on mature densely stocked SPS reefs.
• ULNS biopellets — several kg of biopellets for very low-nutrient SPS tanks.
• Full zeolite protocol — Aquaforest Zeo Mix or equivalent in large format.
• Long-duration anti-nitrate resins — NO3 removal without frequent reload.

Setup and flow

• External pump: not included — suitable pump 1,000-2,500 L/h per media.
• 20 mm fittings: compatible with standard reef plumbing.
• Placement: sump or fish room, strictly vertical.
• Heavy volume: plan a stable support, the full reactor weighs several kg.
• Optimal fluidization: tune the flow to uniformly agitate the media column up to the top without ejecting fines.

Why choose Aquaforest at ReefSolution

• AF110 Media Reactor 2,800 ml — the smaller format for 200-400 L tanks.
• AF150 Media Reactor 7,200 ml — the legacy format for very large tanks (older reference).
• Carbon 5 L — the large-format activated carbon to load in the AF130.

Frequently asked questions

Is a single AF130 enough for a 500 L SPS tank?

Yes — the 5,000 ml capacity loads 2-3 kg of activated carbon and 1-2 kg of GFO simultaneously, giving solid coverage on a 500 L SPS reef for 6-8 weeks before reload. Some aquarists still prefer two separate reactors (carbon + GFO) for independent flow control.

Is the AF130 compatible with the AF Pump 2000?

Yes — the AF Pump 2000 is sized to comfortably fluidize the AF130 across most media. On biopellets at max flow, a slightly stronger pump may be needed depending on load volume.

How long does a load last in the AF130?

It depends on media type and nutrient load. Activated carbon: 6-8 weeks on a 500 L tank. GFO: 8-12 weeks depending on PO4. Biopellets: 6-12 months with partial regeneration. Zeolite: variable, replace when it stops consuming ammonia. Always test before deciding to replace.
