Modern Reef Skim AEROX Ultra‑Pure Spheres CO2 Scrubber Media

Give your reef a breath of fresh air

At Modern Reef, we’re always looking for practical ways to create more stable, thriving reef systems.

In many modern homes, elevated indoor CO₂ levels lead to low pH, slower coral growth, and more nuisance algae. The new Skim AEROX Ultra‑Pure Spheres CO₂ Scrubber Media solves this by cleaning the air going into your protein skimmer – helping to stabilise pH and improve overall tank health.

Why we like Skim AEROX

• Ultra‑pure, medical-grade made explicitly for reef aquariums
  Designed expressly for skimmer air intake – no fillers, just high‑quality CO₂‑absorbing media.

• Helps stabilise and elevate pH
  By stripping CO₂ from the skimmer’s intake air, Skim AEROX can help raise and stabilise your aquarium pH, especially in closed rooms with elevated CO₂.

• Supports coral growth and colour
  A more stable, optimised pH environment benefits SPS, LPS and soft corals, supporting better growth, colour and calcification.

• Helps reduce nuisance algae pressure
  More stable chemistry and improved pH can help reduce conditions that favour the growth of unwanted algae.

• Simple colour‑change indicator
  The media turns from white to violet as it becomes exhausted, so you can see at a glance when it’s time to replace.

How to use Skim AEROX

1. Fill your CO₂ scrubber reactor
   Add 750–1000 ml of Skim AEROX to an appropriate CO₂ scrubber reactor.

2. Connect to your skimmer’s air intake
   Connect the reactor directly to your protein skimmer’s air inlet so that all intake air is drawn through the media.

3. Typical usage on reef systems
   In a 500–750 L reef aquarium, the media is typically effective for 4–6 weeks, depending on:

   • Indoor CO₂ levels

   • Skimmer airflow

4. Monitor and replace

   • Watch for the white‑to‑violet colour change in the media

   • Keep an eye on your aquarium pH
     When most of the media has turned violet and pH has returned to normal, it’s time to replace.

Essential notes from Modern Reef

• Use only in air, on the skimmer intake.

• Do not use directly in aquarium water.

• After use, reseal the zip‑bag tightly.

• Store in a cool, dry place away from humidity.
