# How much Biohome Ultimate do you need for your fish tank?

Biohome Ultimate is one of the best biological filtrations you can get for your aquarium as it will reduce ammonia, nitrites and nitrates. So, how much of this filter media should you use for your fish tank?

You can find out in this guide at Aquarium Blueprints.

Officially, Biohome recommends using the following amount:

• 1 kilogram per 100 liters in a normally stocked tank
• 1.5 kilograms to 2 kilograms per 100 liters in a heavily stocked tank

For a normally stocked tank, you can use the following amount:

• 10 liters = 0.1 kg
• 20 liters = 0.2 kg
• 40 liters = 0.4 kg
• 60 liters = 0.6 kg
• 80 liters = 0.8 kg
• 100 liters = 1 kg
• 116 liters = 1.16 kg
• 120 liters = 1.2 kg
• 160 liters = 1.6 kg
• 200 liters = 2 kg
• 220 liters = 2.2 kg
• 260 liters = 2.6 kg
• 300 liters = 3 kg
• 360 liters = 3.6 kg
• 500 liters = 5 kg
• 600 liters = 6 kg
• 720 liters = 7.2 kg

For a heavily stocked tank, you can use the following amount:

• 10 liters = 0.15 kg to 0.2 kg
• 20 liters = 0.3 kg to 0.4 kg
• 40 liters = 0.6 kg to 0.8 kg
• 60 liters = 0.9 kg to 1.2 kg
• 80 liters = 1.2 kg to 1.6 kg
• 100 liters = 1.5 kg to 2 kg
• 116 liters = 1.74 kg to 2.32 kg
• 120 liters = 1.8 kg to 2.4 kg
• 160 liters = 2.4 kg to 3.2 kg
• 200 liters = 3 kg to 4 kg
• 220 liters = 3.3 kg to 2.2 kg
• 260 liters = 3.9 kg to 5.2 kg
• 300 liters = 4.5 kg to 6 kg
• 360 liters = 5.4 kg to 7.2 kg
• 500 liters = 6.5 kg to 10 kg
• 600 liters = 9 kg to 12 kg
• 720 liters = 10.8 kg to 14.4 kg

If you don’t have any of the aforementioned tank sizes, then you can do the following calculations:

• Multiply the amount of volume, in liters, inside your aquarium by 0.1 kg for a normally stocked tank
• Multiply the amount of volume, in liters, inside your aquarium by 0.15 kg or 0.2 kg for a heavily stocked tank

If you are using the U.S. metric system when it comes to measuring your tank volume, this will translate to the following:

• 1 kilograms per 26.42 kilograms in a normally stocked tank
• 1.5 kilograms to 2 kilograms per 26.42 gallons in a heavily stocked tank

For a normally stocked tank, you need the following amount:

• 2.5 gallons = 0.1 kg
• 5 gallons = 0.2 kg
• 10 gallons = 0.4 kg
• 15 gallons = 0.6 kg
• 20 gallons = 0.8 kg
• 25 gallons = 1 kg
• 29 gallons = 1.16 kg
• 30 gallons = 1.2 kg
• 40 gallons = 1.6 kg
• 50 gallons = 2 kg
• 55 gallons = 2.2 kg
• 65 gallons = 2.6 kg
• 75 gallons = 3 kg
• 90 gallons = 3.6 kg
• 125 gallons = 5 kg
• 150 gallons = 6 kg
• 180 gallons = 7.2 kg

For a heavily stocked tank, you need the following amount:

• 2.5 gallons = 0.15 kg to 0.2 kg
• 5 gallons = 0.3 kg to 0.4 kg
• 10 gallons = 0.6 kg to 0.8 kg
• 15 gallons = 0.9 kg to 1.2 kg
• 20 gallons = 1.2 kg to 1.6 kg
• 25 gallons = 1.5 kg to 2 kg
• 29 gallons = 1.74 kg to 2.32 kg
• 30 gallons = 1.8 kg to 2.4 kg
• 40 gallons = 2.4 kg to 3.2 kg
• 50 gallons = 3 kg to 4 kg
• 55 gallons = 3.3 kg to 2.2 kg
• 65 gallons = 3.9 kg to 5.2 kg
• 75 gallons = 4.5 kg to 6 kg
• 90 gallons = 5.4 kg to 7.2 kg
• 125 gallons = 6.5 kg to 10 kg
• 150 gallons = 9 kg to 12 kg
• 180 gallons = 10.8 kg to 14.4 kg

If you don’t have any of the aforementioned aquarium sizes, then you can do the following calculations to get the right amount of Biohome Ultimate in your tank:

• Multiply the amount of volume, in gallons, inside your fish tank by 0.04 kilograms for a normally stocked tank
• Multiply the amount of volume, in gallons, inside your fish tank by 0.06 kilograms or 0.8 kilograms for a heavily stocked tank

If you would rather used pounds instead of kilograms to measure Ultimate, then 1 kilogram is the equivalent to 2.2 lbs.

If the calculations are too complicated for you, then you can simply add as much Biohome Ultimate as possible in your fish tank as you like. This is because you can never have too much biological filtration in your aquarium.

Along with the compartments of your filters, you can also put Biohome Ultimate directly into your fish tank. Ideally, you should place the filter media in a filter bag as it will make removal easier for maintenance.
