What Causes White Algae In Fish Tanks?

There are several things that can contribute to the growth of white algae in fish tanks. The most common include:

1. Too Much Light 

White algae thrive in aquariums that are brightly lit. If you have an aquarium that is near a window or in direct sunlight, this could be the cause of your problem.

2. Incorrect pH Levels 

The ideal pH level for a freshwater aquarium is between 6.5 and 7.5. White algae can start to grow in tanks with pH levels that are outside of this range, according to Pets on Mom.

3. Excess Nutrients  

White algae also love high levels of nutrients, such as nitrates and phosphates. These nutrients are often found in tap water, so if you’re not using a good quality filter, they could be building up in your tank and causing the algae to grow.

4. Poor Water Circulation 

Poor water circulation can cause pockets of stagnant water to form in your aquarium. These areas are the perfect breeding ground for white algae.

5. Overcrowding 

As Fishlab says in their article, white algae can also grow if there are too many items or fish in your fish tank. This is because there are more fish producing waste, which means more nutrients in the water for the algae to feed on.

How To Treat White Algae In Fish Tanks

Treating white algae in fish tanks is not difficult, but it does require patience and consistency. Here are some things you can do to get rid of white algae.

1. Identify The Cause

The first step in treating white algae is to identify the cause. As we mentioned above, there are several things that can contribute to its growth. Once you know what is causing the algae to grow, you can take steps to correct the problem.

2. Assess the Case Severity

Bad Mans Tropical Fish advises determining the extent of the white fungal infestation in your tank before moving forward with a treatment plan. If your fish tank only has a few white fungal spots, you can try moderate water changes and deep cleaning. If the white fungus has spread to your tank’s flora and fauna, you’ll require a more comprehensive treatment approach. 

3. Increase The Water Flow

White algae thrive in stagnant water. By increasing the water flow in your aquarium, you can make it a less hospitable environment for the algae.

4. Remove Debris

 White algae often grow on debris, such as dead leaves or fish waste. By removing this debris from your tank, you can help to prevent the algae from spreading.

5. Vacuum The Gravel

Vacuuming the gravel is another effective way to remove debris and waste from your aquarium. This will also help to increase the water flow in your tank.

White algae can be a nuisance, but with a little effort, it can be removed from your fish tank. By taking steps to identify and correct the problem, you can keep your aquarium looking its best.
