Aquaforest AF Air Scrubber

Aquaforest AF Air Scrubber

Aquaforest AF Air Scrubber is a CO2 air scrubber reactor that reduces carbon dioxide in the air drawn into your protein skimmer, helping to stabilise pH in reef and marine aquariums. It suits reefkeepers whose pH dips because of high CO2 levels in the room air, and who want steadier conditions for coral growth and overall system health.

Why CO2 in Your Air Matters

Carbon dioxide (CO2) levels have a direct effect on aquarium pH, and low pH caused by high CO2 concentrations can seriously affect coral growth and the health of the whole system. The AF Air Scrubber reactor and its absorbing media help prevent these harmful fluctuations by removing CO2 from the air before it reaches the skimmer and the aquarium.

Key Benefits

• Reduces CO2 and increases pH
• Stabilises day/night pH levels
• Helps prevent sudden changes in dKH
• Compatible with a variety of skimmers
• Easy to use, assemble and disassemble
• Body made from high-quality white and transparent acrylic
• Colour-changing media makes it easy to see when replacement is due

Design Features

• Moistening sponges: the base of the reactor holds three cut-to-size sponges, designed to be soaked in RO water. They moisten the air and improve media performance. Lab tests indicate this design significantly extends the life of the media.
• Bottom-to-top airflow: CO2-filled air is pulled through the sponge layer at the bottom, then channelled up through a grid so the highest amount of CO2 can be removed before the air enters the skimmer or reef aquarium. A flap and seal are installed to maintain proper airflow suction from bottom to top.
• Protected media: the media sits between layers of special dust-absorbing sponges at the top and bottom of the reactor.
• Smart-twist lid: a cap on the lid twists open for quick, easy access to the interior of the reactor.
• Visible media use: because air flows from bottom to top, the colour-changing media is used up gradually from the bottom to the top. This makes it easy to see when it is time to replace it.
• Skimmer connection: a 10 mm (⅜") hose connection on the outer part of the lid connects the reactor to a protein skimmer.

How to Use

• Soak the three sponges in the base of the reactor in RO water so they can moisten the incoming air.
• Use the twist-closure cap on the lid to open the reactor and access the interior.
• Replace the media before the colour has completely changed.
• Connect the reactor to your protein skimmer using the 10 mm (⅜") hose connection on the lid.
• Within a few days, signs of the media working should become apparent, with pH rising as CO2 is absorbed.

Expected Results

The AF Air Scrubber can raise pH by ~0.2 – 0.4 and help stabilise it in the range of 8.0 – 8.4. For the most effective removal of CO2 from the air drawn in by the skimmer, use it together with the Aquaforest AF Air Scrubber Media cartridge.

Frequently Asked Questions

Does the AF Air Scrubber come with the CO2 absorbing media?
No. The CO2 absorbing cartridge is not included. The reactor is recommended for use with the Aquaforest AF Air Scrubber Media cartridge for the most effective CO2 removal.

How much can it raise my pH?
It can raise pH by ~0.2 – 0.4 and help stabilise it in the range of 8.0 – 8.4. Signs of the media working should be apparent within a few days as CO2 is absorbed.

How do I know when to replace the media?
The media changes colour gradually from the bottom to the top as it is used. Replace it before the colour has completely changed.

Why do the sponges need to be soaked in RO water?
The three sponges in the base moisten the incoming air, which improves media performance. Lab tests indicate this design significantly extends the life of the media.

What size hose does it connect with?
The hose connection on the lid is 10 mm (⅜"). It connects the reactor to your protein skimmer, so check that your skimmer's air intake suits this size.

Will it help with day/night pH swings?
Yes, it is designed to stabilise day/night pH levels and help prevent sudden changes in dKH by removing CO2 from the air drawn in by the skimmer.
