Benefits of Pothos Plants in Aquariums

There are several benefits of having pothos plants in aquariums. Here we have shared some of its benefits –

Eradicate Nitrates

Like all freshwater aquarium plants that absorb nitrates, this plant is known for its nitrate-absorbing capabilities. However, the pothos has a higher rate of absorbing nitrates than other plants – 20 – 40 ppm.

Whenever there is an increase in nitrate content in the water, your fish may get sick.  To save your fish and maintain nitrate levels, add a pothos plant to your aquarium today!

Shade

Some aquarium fish need a bit of shade to live. Fish like the betta and angelfish need a bit of shade to live properly in an aquarium.

Adding a pothos plant will give them their shade and help to imitate their natural habitat.

Removes Algae

The formation of algae is the most common phenomenon in aquariums. The presence of minimal algae is considered to be healthy for tanks.

However, too many algae can cause some serious problems to your fish and affect the water content in the tank. Algae forms when the water has high nitrate content and waste in the tank.

To balance the nitrite, add a pothos plant to the tank. Pothos plants will absorb the nutrients that promote algae formation for their own good, and this will prevent algae formation.

Aeration

Pothos plants promote optimum aeration in the tank.

When photosynthesis takes place in the tank, the carbon dioxide released by the fish has used the plants, oxygenates the tank in return!
