Algae Busters: How to control algae in your aquarium

Algae growth can wreak havoc on the aquarium you have worked hard to create. Luckily, there are multiple ways to prevent or diminish algae. Following our simple suggestions will keep your aquarium, and the life inside of it, in great shape.

As mentioned in prior blogs, in order for plants to reach their full potential in growth and nutrition, they must have a continual supply of water, CO2, and nutrients. Making sure you are using the right light for your tank and measuring the right dosage for CO2 and plant nutrients will prevent algae buildup. Once plants absorb all of the nutrients that they can, the rest is left to build up in your aquarium. Be sure to follow proper dosing recommendations and check CO2 daily, while also observing plants for signs of algae growth.

Changing the water in your aquarium is one of the most important ways to keep nutrients from building up. Water changes ensures that there is not a build up of leftover nutrients in your aquarium. It is best to choose the plants that work with the type of water that you already have instead of the other way around. Regular, large water changes help to flush out excess nutrients and keep algae at bay.

Putting algae eaters into an established plant aquarium will reduce the different types of algae that tend to grow. Shrimp, snails, and algae-eating fish prefer different kinds of algae. The bigger variety of them that you have, the easier to prevent an algae buildup as there are different types of algae.

The following is a list of snails, shrimp and fish that are great for taking care of algae:
