Algae is not a bad thing
Before we get started we just like to say that algae is not a… bad thing. It doesn’t harm the fish or damage the aquarium water. Getting rid of algae can be seen as a purely aesthetic exercise. Some aquarists even let certain species of algae grow in their aquarium to give it a natural look.
Granted, if it’s growing on the glass it can block the display of the aquarium, but biologically it’s harmless.
As we mention below, plants help to prevent algae growth as they remove the nitrates that algae feeds on from the water. But, to be fair, the algae does help to remove the nitrates in the first place.
However, depending on the level of the nitrates this removal can be marginal, so it shouldn’t be seen as a standalone method of reducing nitrates in the aquarium water.
If you do decide you want to clean the algae from your aquarium, check out the 7 tips below. If you’ve got any of your own algae-cleaning advice, let us know in the comments.

- Add live plants to your aquarium
- Be well-equipped, and don’t be afraid to improvise.
