Algae is a common problem in freshwater aquariums but it is actually a fairly simple problem to solve. There are many different types of aquarium algae and not all algae eaters will eat every type. Algae is a living thing and, as such, it requires certain nutrients to grow. When you think of aquarium algae, you probably picture a fluffy green growth. While this is certainly one kind of algae, there are actually many different types that you could find in an aquarium. The most common types of aquarium algae are Brown Algae, Green Hair Algae, Brush Algae, Blue-Green Algae and Green Spot Algae.
How to clean up Algae in your tank?
Getting rid of algae in your freshwater tank can be tricky and you need to be careful what method you use. Commercial water treatments can sometimes do more harm than good by throwing your water chemistry out of whack.
If you know what type of algae you have growing in your tank, you can choose an algae eater that tends to target that specific type of algae. Algae eaters aren’t just fish, they can be anything from snails to aquarium shrimp, as long as they feed on live algae growths.
