What is a Pond Filter?

A pond filter is one of the essential devices that you need to keep your pond clean. Pond filters provide sufficient oxygen into the water and help to keep the water clean and free from algae. Pond water becomes turbid and dirty with time a pond filter keeps the water clean. If you own a fish pond or koi pond in your garden, then a combination of a preliminary mechanical filter and a biological pond filter can go well for you.

Wondering what kind of pond filter and filtering equipment will be best for your pond? Here is the answer for you. The choice of pond filters entirely depends on your pond structure, size, and nature of the species you have in it. Here we are going to discuss everything about the best pond filters for you.

Why Your Water Feature Requires a Pond Filter?

As we all know, our backyard ponds are entirely human-made; they depend entirely on us when it comes to cleaning and maintaining a healthy ecosystem. A high-quality pond filter takes the responsibility of all the hard work that needs to keep a pond or some other water features.

The ecosystem of every pond or water feature has a nitrogen cycle. The process starts with the waste and leftover food sinking to the bottom. All those waste materials eventually get converted into ammonium and nitrate compounds. These compounds get absorbed by algae and plankton in the water. While the nitrogen is essential for bacteria growth, excessive growth of the nitrate compounds is not suitable for the fish presence in our pond. Not only that, but also the excessive bacteria growth can turn the crystal clear water of your lake into greenish so, there remains a fair bit of chance that your water feature loses its beauty with time if not appropriately maintained.

Therefore you need a pond filter just to keep your pond clean and healthy for all the living organisms there!

There are several types of pond filters available in the market. Depending on your need you just have to choose the best one. Below we have discussed how you can select the right pond filter.

How to Choose The Right Pond Filter for Your Needs?

With the summer season taking shape you must already get a gentle tickle by picturing yourself lavishing the spare time watching your fishes in the pond. But before that, having a healthy pond ecosystem is essential. Here are the key things you must consider before you choose the best pond filter for your water feature.

  • Firstly, Set a budget

There is no point browsing through the hundreds of Pond filter models without working out on your budget. So firstly, know precisely how much you want to invest in your backyard pond or water feature. Filtration is one of the essential parts, thus reducing the budget of pond filtration is not something that is going to help in the long run.

  • Figure out the Amount of Filtration You Need

Knowing the amount of filtration need is essential before choosing the best pond filters for your water feature. Here is how you can estimate the amount of filtration your pond requires.

  • Firstly, figure out the volume of your pond
  • For an approximately square, rectangular or circular shaped pond, you can use the following formula and easily figure out the volume:
  • Length X Width X Depth = Volume
  • For example, suppose the length of the pond is 10m, width is 8m, and depth is 1.2m.
  • Therefore, the volume will be 10m X 8m X 1.2m = 96.0 ㎥ = 96000 Litres

After knowing the approx volume of your pond, it is time to calculate the filtration requirement. If you want to keep normal fish as in goldfish you just need to double the approx value of your pond. Because of the amount of waste in the pond is doubled by the fish, which means your filter will have to deal with more amount of things in the pond.

However, if you are looking to keep koi fish in the pond, then the filtration requirement changes. For Koi fish, you will have to quadruple the figure. The reason behind this is Koi fish produces a considerable amount of waste material in your pond.

Additionally, having the information about the type of pond filter system is essential before you choose the right one. Therefore here are the types of pond filters you can choose from.
