Aquaforest AF Air Scrubber 2.3L

Efficient CO₂ Reduction for pH Stability in Reef Aquariums

The Aquaforest AF Air Scrubber 2.3L is a powerful and effective solution to raise and stabilize pH levels in marine aquariums. Designed to combat CO₂ accumulation, especially in poorly ventilated environments, this air scrubber helps create ideal conditions for coral growth and health by minimizing daily pH swings and supporting a stable dKH.

Features & Benefits

• Reduces CO₂ concentration drawn into the skimmer

• Raises and stabilizes pH (typically by ~0.2–0.4)

• Minimizes night-time pH drops for better reef stability

• Innovative 3-sponge humidification base enhances media efficiency

• Top-to-bottom airflow ensures even media usage and easy monitoring

• Quick-access twist cap for simple refills and maintenance

• Premium acrylic construction for durability and aesthetics

• Compatible with standard 10mm (⅜") skimmer hose connections

• Prevents sudden changes in alkalinity (dKH)

How It Works

By channeling air through a moist sponge layer and into the CO₂-absorbing media, the AF Air Scrubber effectively removes CO₂ from incoming air. This reduces acidification of your aquarium water, resulting in better coral calcification, coloration, and vitality.

• Color-changing media indicates usage progress

• Clear acrylic body allows easy monitoring

• Replace media before full color change for best performance

• For best results, pair with AF Air Scrubber Media (sold separately)
