How much bio media you should use per gallon in your tank

When you are purchasing bio media for your fish habitat, you may notice that different manufacturers will specify different filtration needs. You may even decide to do some further research to see how each different bio media option performs. However, you always need to take these reviews with a grain of salt because every tank has different requirements.

The gallons your tank holds aren’t the main thing you need to consider when it comes to bio media. In all actuality, the amount of water used in your tank has very little to do with how much bio media you should be using. The number of fish in the tank, though, along with how big the fish are and how often they get fed are the determining factors you should instead be placing more focus. 

For this reason, you may want to consider using more than 0.02 kg/gallon of bio media in your setup. If you have multiple fish or larger-sized fish, you will definitely need to use more than suggested to keep the tank in good condition.

Is it possible to use too much bio media in a fish tank?

When it comes to using bio media, it’s very unlikely that you will add “too much” to the fish tank. Bio media is typically placed in the filter of a tank, and most people place the bio media in a mesh holding bag. A lot of tank owners will simply fill the bag up with their preferred choice of bio media and then place it in the filter and leave it be. 

Using too much bio media has no negative effects, as long as you know when to change it out. However, not using enough bio media will leave too much waste in the fish tank. This waste puts your fish at risk of getting sick with results that could be fatal. This is why, if you’re not sure exactly how much bio media to use for your specific aquarium habitat, simply filling a mesh bag to place in the filter is a good option for when you first start using it.
