WHAT LEADS TO EXCESS ALGAE?

There are several factors that lead to algal overgrowth.

These are biocides that, when used improperly, can damage and kill plants and fish. It is not a long-term solution because it only temporarily converts algae from a green organism into a free-flowing nutrient that will become algae again the moment the chemical dissipates.

It can also increase ammonia levels because of the rapid death of algae.

Coagulants, which are also commercially sold, are safer. They are relatively effective when their instructions are followed properly. However, they have a short shelf life.

I am not a fan of these products and would suggest using a more natural process of controlling algae.

These are a safe and proven way of reducing free-floating algae. A properly performing UV clarifier can achieve a 99% reduction without adversely affecting your pond’s inhabitants. They are easy to maintain and available in various wattages to match any pond size.

They are best used with plants and an active biofilter with beneficial bacteria. Their bulb should be changed every 12 months. Make sure the pump with the UV light is not pumping too much or too fast, since the water passing through the UV is of key importance.

I use UV lights to maintain ponds exposed to sunlight. A downside is their extra cost, They are also not needed in a healthy pond system. I recommend using UV lights in emergency situations only.

This is the correct way to bring about a balanced ecosystem.they can be set up through a well-designed filtration system.

They use excess nutrients in the water and compete with algae. However, they may die if the pond is cleaned, drained, or filled with excess amounts of new water.

These are high-density filters used for mechanical filtration. They trap the algae before they reach the biological section of the filtration system.

Make sure to regularly clean the media to prevent clogging.
