Fish rearing beginners are sometimes at pains to understand why pond filters are necessary for their koi ponds. They equate theirs to a natural lake but forget that there is a significant difference between the two.
A natural pond has a physical mechanism that maintains the best ecosystem for the fish to thrive. Typically, a natural lake has a stream that brings water into it and sometimes another that takes it away. This helps flush fish waste and maintain the necessary balance between the different microorganisms, plants and the population of fish required.
To achieve the same level of an ecosystem in your garden pond, you will need a filter – and the best one for that matter.
Why you should have a Pond filter
One of the best reasons for having a pond filter is to keep the water clean and clear for the fish to do well. Natural ponds have plants that the fish feed on, and soils, as well as, rocks where microorganisms can be found. These microorganisms form the natural pond cleaning system by working on the dead plants and animals that may make the water inhabitable for the fish. But why can’t they do the same for artificial ponds?
The answer to this question is simple. Your garden pond may not have soil and plants. This means that the conditions necessary for the microbes are insufficient. Fewer microorganisms mean ineffective natural pond cleaning system. The dead animals, plants, and poop will then make the water smelly and cloudy. To make matters worse, your pool will not have an inlet to replenish the necessary ecosystem for your fish.
A pond filter helps keep the appropriate aquatic environment making the fish feel at home. They also make the pond smell-free and clean to your benefit, and of those coming to see what you have been up to lately.
What to Consider when Choosing the Best Pond Filter
- Your pond size: the type of filter you go for is very much dependent on the volume of the pond and the number of fish. Of course, the more fish you have, the more the need to clean it frequently – you know, the poop, and all. The size of the pond is measured in gallon capacity. It does not mean that you can go for a more substantial capacity for more efficiency. Determine the volume that your pond holds and make your decision on the filter based on that, and your fish will be glad you did.
- The type of filtration: depending on the current situation of your pond, the pond filter may utilize a combination of systems such a chemical, mechanical and biological. However, the most common among them include biological and mechanical filtration systems.Biological filtration is critical for the maintenance of a healthy ecological balance within the pond. Mostly, the filtration process works to remove any harmful microorganisms that would threaten the well-being of your fish and water ponds. It is not unusual for the biological and mechanical systems to combine and create the most appropriate environment for the fish.The mechanical filtration works like a sieve by picking any organic debris in the water. This waste may be from the water plants or from outside the pond like grass and leaves. It can also include pieces of food that people feed the fish.
- The position of the pond filters: pond filters can further be categorized as either external or submersible. Some filters are designed to be inside the pond and others outside. It will depend on your preference and budget.The submersible filters work within the pond and depending on the condition of your pond, regular maintenance and cleaning is necessary. External filters are not within the pond but on the landscape. They are easier to clean and maintain. However, you may need to employ a variety of methods to conceal it.
- The design of the filter: there is a wide variety of filter shapes and sizes.You will commonly find pressurized filters in koi ponds. They utilize both the mechanical and biological filtration processes. These filters can either be external or submersible and work by using a higher pressure to clean the pond. Therefore, they will need an electrical outlet to operate.Canister filters are commonly placed on the pond’s water level. They are usually biological and are easy to maintain, as well as, clean.Box filters function by allowing water to pass through different stages of the filter media. They utilize both biological, as well as, mechanical filtration systems to clean the pond. Typically, box filters are submersible and so require more maintenance and cleaning.
