Diatoms are a type of algae that are common in aquariums. They can cause discoloration of the water and can be difficult to remove. In this article, we’ll discuss whether Phosguard, a popular aquarium filter media, can be used to remove diatoms.

What are Diatoms?

Diatoms are single-celled organisms that are found in both fresh and saltwater. They are a type of algae that have a unique silica-based cell wall. Diatoms are a common sight in aquariums, and while they are generally harmless, they can cause a discoloration of the water.

Does Phosguard Remove Diatoms?

Phosguard is a popular aquarium filter media that is designed to remove phosphate and other nutrients from the water. While it is not specifically designed to remove diatoms, it can be effective in reducing their numbers. Phosguard works by trapping the diatoms in its porous structure and removing them from the water. The filter media should be replaced regularly to ensure that it is functioning properly and removing the diatoms.

In conclusion, Phosguard can be effective in reducing the number of diatoms in an aquarium. However, it should be used in conjunction with regular water changes and other maintenance to ensure that the diatoms are kept under control.
