How You Can Control Algae Growth On Plants In Your Aquarium

Algae is an all-too-common problem in aquascaping, which is why constant vigilance is important in order to keep giant algae blooms at bay. Not only can algae blooms be tough to clean, they can also be harmful to your aquarium plants and animals. So, if you’re interested in reducing algae growth, follow these tips and find your tank’s natural balance.

Stop Overfeeding

Overfeeding fish is easy to do. While feeding time may be an aquarium hobbyist’s favorite time to interact with fish, overfeeding can stimulate aquarium algae on your plants. With excess fish waste due to overfeeding, your water’s nitrate and phosphate levels will increase, leading to blue-green and red algae that can be detrimental to the entire ecosystem in your aquarium. To avoid this, stick to recommended food quantities at regular intervals, and be sure to remove any uneaten food.

Partial Water Change

Partial water changes go a long way in keeping the water quality constant in your aquarium. Water changes need to be done weekly to keep your fish healthy and algae at bay. Of course, a little algae is normal, but it’s important to take care of an algae problem before your entire tank is green.

Test Your Tank Water

It is imperative to have the correct water conditions to decrease aquarium algae on plants and walls. Check for toxic compounds such as chlorine and chloramine, as these are quite common in tap water.  Once that’s done, verify your aquarium’s water for any excess nitrites, nitrates, fluctuations in alkalinity, as well as its hardness, measured on the pH scale. Also, test your tank’s temperature regularly.  Maintaining sanitary conditions will keep animals healthy and reduce algae growth.

Limit Unwanted Light

Algae grows and thrives through photosynthesis, which is aided by lots of light. By limiting unwanted light, you are also limiting the food source for the algae. Make sure your tank is away from any direct sunlight, which can also be stressful for fish. Fish need light in the day to stay healthy, but lights can be dimmed and or off in the evenings.

Add More Plants

Living plants are a great addition to an aquarium because they can keep algae at bay since they compete for the same food sources. Healthy plants are better at soaking up nutrients than algae. Of course, certain aquarium algae will grow on your plants, but balancing the correct combination of fish and plants can decrease algae in your tank.

Introduce Algae-Eating Animals

Algae-eating fish aren’t the complete answer to algae issues, but they can deal with small issues and maintain algae. Be sure to research how large algae-eating fish are going to grow. Generally, you should opt for fish that will take care of aquarium algae on your plants, but won’t ruin them completely. Some species that aid in this includes little schooling otocinclus or small shrimp.
