A Comprehensive Guide To The Best Pond Filter

A backyard pond is a great spot where your family can find temporary relief from those boiling hot days in the summer. It can be a languid oasis that is completely free from the hustles and bustles of day-to-day living. But this can only be achieved when you have a properly operating pool filter. Equipped with advanced features, the filtration system plays a key role in keeping your pond water always clean and clear. To help you make the right choice, I’ve created this guide with some useful tips and reviews about the best pond filters available.

What do we need a pond filter?

A pond filter is an essential component that can keep your garden paradise from becoming an unusable swamp. It helps get rid of toxic chemicals, decaying organic matter, excess food, fish waste, and other debris. If these elements build up over time, they would cause annoying smells and murky or green water. Also, fish in the pond can be affected due to increasing levels of poisons.

Key considerations and features to look for in a pond filter

a) Types of pond filter

You can choose from one of three kinds of pond filter: biological, chemical, and mechanical. Biological systems use bacteria to remove ammonia coming from fungi, waste, or food, while chemical units use a resin or filter media to remove some nutrients or chemicals with excessive amounts. Mechanical filters drive water through some materials that can catch debris and particles.

b) Flow rate

Flow rate is the amount of water a filter would pass through it per hour. For efficient filtration, a pond filter should pass 4 times the whole volume of the pond each hour. It is often better to go for a unit with a higher flow rate.

c) Ease of maintenance

A filtration system requires periodical replacements. However, some units are easier and cheaper to change than the others, which reduces the costs and effort of maintenance.

d) Size

To choose the right size of pond filter, you need to measure the area of your water area. With these measurements, just follow the instructions of the manufacturers and select a suitable option for your needs.

How to use a pond filter

Just like any other appliances, the first thing you need to do when using a pond filter is to read the manual guide and user instructions from the manufacturer to learn how to use it correctly.

After unpacking, you need to assemble all components and put the filter under the water inside the pond. Once one end of this machine is the pump equipped with tubing attached to the discharge side. You can attach this discharge side with a barbed-threaded or pipe-threaded nipple where the tubing could be connected. Then, it is necessary to attach the tubing to an intake area of the pond filter.

A benefit of operating a pond filter is that this submersible machine can be out of sight and hidden anywhere inside the water. Also, most of them feature black colour, so you won’t have to worry about spoiling the overall landscaping.

Depending on the sizes of your pond and working capacity of the filter, you can run a pond filter between 10 and 15 hours per day. It is important to check the pump pre-filter regularly to ensure it has good flows. For biological units, keep in mind that it might take them a few weeks to become fully active.

When fish in your pond grow in size, you might have to consider increasing the power and size of the filter. This is because more fish means there will be more waste and debris, which would make the water turn murky or odorous. Also, avoid overfeeding your fish as it would make it harder for the pond filter to clean the water adequately. It is better to feed the recommended amount.

Ideally, you should clean your pond filter at least once per month. Just disassemble all components and use a solution of cleaner and lukewarm to clean each part thoroughly. Rinse again with clean water and check for any remaining debris. Regular cleaning is important to ensure smooth and efficient operation, as well as prevent the blockage of the pump or hose.
