To avoid the formation of algae in the first place, you need to remember the following steps while taking care of your aquarium.

Steps to stop Algae Growth

  1. Avoid excessive light

Light exposure to your fish tank must not exceed more than 6–7 hours for maximum. Moreover, while selecting your tank’s location, ensure that it is not exposed to direct sunlight.

  1. Regular Water Changes

Replacing at least 25% of aquarium water every week will remove excess waste from the tank. Furthermore, make sure to clean well using a gravel vacuum to remove any debris or food particle underneath the substrate.

  1. Avoid Overfeeding fish.

Feed the fish twice a day for not more than 1–2 minutes. The surplus food will decay and ultimately provide nutrients for algae growth and development.

  1. Balance pH level

Maintaining a correct balance of pH level, water hardness, and water temperature are essential to avoid algae formation.

  1. Efficient Filtration System

Equipping your tank with an efficient filtration system ensures the maintenance of a clean tank. A clean and healthy aquarium forbids algae growth.

  1. Clean your Gravel and Tank base

Use water siphons to eliminate any hidden debris and waste of fish food, which might aid in algae formation.

Furthermore, the use of water pumps or an effective aeration system is also compulsory as a significant amount of oxygen can kill off any blooming algae.

As prevention is always better than growth. Thus, the above-mentioned conditions will help you to prevent the formation of algae.
