Filter Media Calculator – Accurate Aquarium & Pond Filter Media Sizing Tool

The Filter Media Calculator helps aquarium and pond owners calculate the correct amount of filter media required for efficient water filtration. By entering your tank or pond volume, this tool provides accurate recommendations for biological filter media, activated carbon, and filter sponge in both liters and kilograms.

This calculator is suitable for freshwater aquariums, marine reef tanks, koi ponds, sumps, and canister filters. Correct filter media sizing improves biological filtration, water clarity, and overall fish health.

What This Filter Media Calculator Helps You Do

• Calculate biological filter media volume for beneficial bacteria growth
• Determine the correct amount of activated carbon for toxin and odor removal
• Estimate filter sponge requirements for mechanical filtration
• Avoid overloading or underfilling aquarium filters
• Improve ammonia control, nitrate reduction, and water clarity

Why Accurate Filter Media Calculation Matters

Using the correct amount of filter media helps prevent ammonia spikes, cloudy water, poor biological filtration, and fish stress. This calculator removes guesswork and helps you build a balanced and efficient aquarium filtration system.

⚠️ These results are general recommendations. Always adjust based on fish stocking levels, filter design, flow rate, and manufacturer guidelines.
