Pond Filtration
Filtration is needed to eliminate muck, debris, and biological waste from the water that are unhealthy for the pond. A properly installed filtration system will pull water from the bottom of your pond and circulate it with essential nutrients and oxygen throughout the feature.
There are natural ways of filtering, but help from manmade filters and pumps help speed up the process of filtration. Even if your pond is solely decorative, a filtration system will help prevent stagnation, reduce algae growth, impede insects, and clean the water.
Types of Filtration
Pre-filters
Remove debris before it enters the pump, protecting the pump and thereby leading to a longer pump life and better performance.
Mechanical filters
Work with a pump to move the water and catch large and small pieces of debris.
Biological filters
Use beneficial bacteria to naturally break down organic decaying material and aid in the growth of beneficial bacteria.
Pressurized filters
Typically combine mechanical and biological filtration. The pressure in the filter pushes the water through the filter so that the maximum amount of debris is removed and it also allows you to return the water back to the pond through a spitter or small waterfall.
TotalPond Filtration
Some major factors to consider when choosing a pond filter include: the volume of your water feature, the water depth, as well as the number of plants and fish that are present in it. The filtration system is almost certainly the most important piece of mechanical equipment in your pond, so spending more on a system that is easy to maintain and of the best quality is to your advantage.

Ultraviolet (UV) Light
Ultraviolet (UV) Light Technology maintains water clarity and a healthy pond environment for plants and fish. Water is pumped through a carefully calibrated UV chamber at just the right speed to provide maximum exposure. As water passes over the UV bulb, it’s cleaned of microorganisms that cause green, murky water. The results are a crystal clear and healthy pond you can enjoy all year round.

Tubing
Tubing is a conduit, allowing water to flow from a pump to the rest of your pond equipment. For best performance, we recommend using the largest tubing size option.
