How Does Pond Filtration Work?

How Does Pond Filtration Work

Your pond might often get accumulated with elements like dirt, sewerage and biological wastes. Pond filtrations eliminate these accumulated elements to keep your pond free from them.

Their main job is to draw dirty water from the pond, which pulls out the waste materials and pushes those water into the filter. Then the filter filtrates the dirt and then release the clean water back to your pond.

Does All the Pond Require Filtration System?

Fish Pond

Now let’s answer the most common question of all time.

The answer is NO. All the ponds do not require filtration. If you are just planning to create a wildlife environment in your pond with just a couple of fishes then you won’t require a filter. In that case, you should try to focus on creating a natural balance instead.

The process is quite simple but in order to get a properly balanced nitrogen cycle, it takes a lot of time. This is the major reason why most of the people prefer to go for buying filters.

The basic principle is that you will require a lot of plants, which would cover around two-thirds of the area of the pond. These plants along with some bacteria will rot all the organic waste, and kill all the toxins produced by the fishes.

This will help you create a good natural balance in the pond as well as clear your pond. It will take around eighteen months to get a complete naturally balanced ecosystem in your pond.

Know the Best Size Pond Filter For You

Pond Filter

Most of the people have a tendency to for the cheap and small sized filters to keep it within their budget. This actually serves no good purpose, rather leads to improper filtration and causes health problems to fishes.

First of all, you need to find the volume of your pond to know the right filter size. This involves a small mathematical calculation.

Get the length, breadth and height of your pond. Then multiply the three units, i.e. l x b x h. This is your pond’s volume. In a square-shaped pond of each side 10 ft., your volume will be 10 x 10 x 10 = 1000 ft3.

After that, multiply the volume with some number, say p, which depends on the shape of the pond. This will be the gallon capacity of your pond. If the pond is square in shape take p = 7.5 For example, if your pond’s volume is 1000 then your gallon capacity will be 1000 x 7.5 = 7500 gallons.

If the shape of your pond is irregular, take the value of p as 6.7 and for rectangular ponds, take the value p = 7.5.

Again, there are some environmental factors that you should consider. You need to multiply another number which will result in higher gallon capacity for your pond. If the depth of your pond is less than 2.5 feet, then multiply the value with 1.25. Example – our final gallon reading of our previous example will be 7500 x 1.25, which is 9375 gallons.

Once you know all these things, you should consider some other minor factors like:

  • Easy to maintain
  • Less energy consumption
  • String algae control ability
  • Green water control ability
  • Warranty

Types of Pond Filters

When you are looking to purchase a pond filter, you need to make sure that you get the right kind of pond filter. Usually, there are five different major pond filters in the market. Each of them is manufactured to serve some unique purposes. Here are all the five major types of pond filter for you:


In-Pond Sponge Filter

This type of filter is generally used for smaller sized ponds, which can hold around 500 gallons or less. In-pond sponge filters are usually attached to a pump, and to ensure thorough and complete cleaning, an additional bio-chamber is recommended when you use this filter.


Skimmer Type Filter

They catch large sized junks (like dried leaves) before they reach the bottom of the pond and rot there. It pulls the water from the surface of the pond and thus the waste material also comes to filter. The skimmer type filters are generally used for both larger and smaller sized ponds. It starts from 250 gallons of water.


Pressure Filter

Pressure filter is a type of mechanical filter, and works great in small to medium size ponds. This filter draws water from your pond directly by a pump and lets the water pass through a trap which removes the debris from water and releases clean water in the pond. You can also fit this filter under the soil to give your pond a cleaner look. It can serve up to 5000 gallons of water.


UV Sterilizer

UV Sterilizer is not like the typical water filters. You will hear people calling them ‘clarifiers’ more than ‘filters’. They work great killing the microorganisms harboring in your pond including fungi, algae, and also viruses.


Waterfall Filter

This is the final type of pond filter. They can be of great use if your pond is 1000 gallons or less.
