What is chemical filtration and why do you need it in your aquarium?
As the name suggests, this is a filter that specifically removes chemicals from your aquarium.
Now, you may be thinking:
I don’t need that because I don’t have any chemicals in my aquarium!
Well as it turns out, you do…
When most people think of chemicals, they think of man-made ones such as laundry detergent, bug repellent or antifreeze. I’ll agree, none of these should be in your aquarium. 
But it turns out nature is just as good at creating chemicals!
Guess what? All of those are chemicals!
And you can use a chemical filter to remove them from your aquarium.
But chemical filtration can do more than just remove chemicals.
Depending on the type, a chemical filter can also remove other pollutants – some of which are just an eyesore but others of which can quickly kill…
- Heavy metals, such as copper
- Compounds, like sodium chloride (salt)
- Medication used to treat sick fish
- Tannins from driftwood that discolor the water
- Did you know? Many of the pollutants that can be filtered out by a chemical filter can also be removed by water conditioners.
