What is the Distinction among Submersible and External Pond Filters

When you’re establishing up your pond, one of the most essential parts of products you’ll buy is your pond filter. Your pond filter is the following best thing to Mother Nature when it comes to maintaining your fish happy and healthy. In fact, the more money you spend in a well-designed large pond filter, the easier your pond maintenance more than the years.

For effective pond filtration, you need three types of water care: biological, mechanical and chemical. The biological portion of your filter is fine filter floss or bio-balls that house beneficial nitrifying bacteria. The mechanical portion is coarse filter floss that separates waste debris from the pond water. Finally, the chemical portion of your pond filtration is entirely up to you! You can add ammonia chips, carbon or any sort of chemically treated filter pad to improve your water quality. A pond filter can house all three of these components at once for easy maintenance and cleaning.

When looking at filters, you’ll find that there are two basic types: submersible and external. Submersible Swell Uk are placed directly in the water, while external filters are placed outside of the pond. Both have a water pump that must be placed under the water in the pond. Submersible and external filters offer unique features and advantages that you’ll have to consider when deciding which one you want to purchase.

Submersible filters run entirely under water and sometimes come with a water pump connected to the housing unit for easy installation. Most of them have attractive fountainheads that help aerate the water, and some high end models even come with built-in UV sterilization. A big advantage of a submersible pond filter is the fact that it’s hidden under the water. Generally, submersible pond filters are ideal for smaller ponds under 2,000 gallons. A drawback to submersible pond filters is that they are difficult to reach for cleaning and maintenance. To clean the filter pads (recommended once a month or more) you will need to physically enter your pond to reach your filter.

A standalone submersible pond filter (no attached water pump) can run as low as $40, but you will have to buy a water pump. An all-in-one submersible system (pump included) starts around $180. The best part about a submersible filter is no external plumbing, so installation is a snap.

External pond filters are housed above ground near the pond, receiving water from a pump inside the pond. External pond filters offer very easy maintenance and cleaning routines. There’s no need to get wet when you’re cleaning an external pond filter, since everything is above ground. They are excellent for ponds over 2000 gallons. A common drawback to most external filters is that they are hard to hide. Some pond owners overcome this by building attractive housing for the filter or by burying the bottom half of the filter in the ground. External pond filters also need to be properly plumbed to the water pump inside the pond. This can be intimidating for new pond owners.

An external pond filter can start as low as $80. Larger ones with built in UV can run much higher- over $250. All external filters need to be plumbed to the water pump inside the pond and the return, so you have to factor in plumbing costs too.
