Start slow: Begin with half the recommended amount and monitor your tank over 24–48 hours before increasing. Adding too much carbon all at once can shock sensitive corals and affect water chemistry, including pH and ORP. Replace carbon every 7–14 days for regular use, or every 3–7 days when targeting specific contaminants.

Carbon Filter Media Calculator

Activated carbon is essential for keeping your reef aquarium water crystal clear. It removes organic pollutants, yellowing compounds, odors, and residual medications, helping maintain optimal conditions for your corals and fish.

This calculator helps you determine the right amount of carbon media for your system, based on your tank volume and the specific product you use.

Start Slow: Recommended Usage

Note: The calculated amounts are starting points and may need adjustment based on your tank’s needs.

We recommend beginning with half the recommended amount and monitoring your tank over 24–48 hours. Gradually increase if needed to achieve the desired water clarity and chemical balance.

Adding too much carbon all at once can shock sensitive corals and impact water chemistry, including pH and ORP. For best results, use smaller amounts spread over 1–2 days or more, and monitor parameters closely.

Plan to replace carbon every 2–4 weeks or when effectiveness diminishes.

How This Calculator Works

Simply enter your aquarium volume, and the calculator will recommend the appropriate carbon amount based on the product’s specific dosing guidelines. This ensures you get the benefits of carbon filtration without the risk of overdosing.
