Your pond filtration system is among the most important pieces of equipment in keeping your pond’s ecosystem healthy and active. There are several different types of filtration methods and associated systems to keep your pond water clean. Depending on the size of your pond and the type of filtration system you select, the setup can range from a few minutes to a few hours.
Types of Pond Filtration Systems
- Mechanical - Uses equipment such as pumps and filters to clean the water
- Chemical - Uses carbon resins formed in a pad or bag to absorb organic and inorganic contaminants
- Biological - Uses the natural processes of bacteria to break down harmful levels of ammonia that can build up in your pond from decaying organic matter
Let’s take a look at how to set up one of the more complicated mechanical systems. This type of pond filtration system can support a pond of up to 20,000 gallons.
Step 1 – Determine the Layout
Consider the design of your filtration system at the same time you design your pond. That way, you can determine the best way to lay out the piping for the filter and pump equipment. This will help eliminate the toughest part of the job, which involves digging trenches for all this piping.
Step 2 - Install the Plumbing
Once you’ve determined the best layout for the plumbing, you can lay the piping to the pump and filter. You are creating a closed-loop system in which the pump will force the water from the pond through the filter and then back to the pond again.
Step 3 - Install the Electric
Pumps for pond filtration systems of this size usually run on common household power, which is 110 volts and between 10 and 30 amps. The wire size and circuit breaker you will need for this job will depend on the pump you select and its specific power requirements. Remember that when running any electric cords outdoors, you should run all wiring in conduit and use weatherproof wiring and connectors.
Step 4 – Set Up the Equipment
Once all your plumbing and electric has been installed, you can set up your pump and filter and make the final connections. Determining the right size pump has everything to do with the number of gallons your pond holds. A good rule of thumb is to choose a pump with a flow rate that allows all of the pond's water to be recirculated within 60 to 90 minutes. Selecting a filter requires some research as to the different materials and mediums you can use to remove the algae and muck from your pond. You can add specific chemicals to the filter reservoir to target specific pollutants.
