Your pond has the potential to smell pretty bad. If you’ve ever been out to a pond in nature or smelled a swamp, you know how bad they can smell. The smell of a swamp or stagnant pond comes from the smell of anaerobic decay that happens in very wet environments. When you are operating a controlled environment, such as a garden pond, you know that you have to make sure you reduce the amount of organic matter that can decay. This matter consists of sloughed off fish scales and dying plant matter. To reduce the smell coming from your pond, you should look into a filtration system. These systems come in two basic varieties, flow-through pumps and pressure pumps.

Flow-Through Pumps

A flow-through filter is a filter in which the pump feeds water through the filter. They are placed at the highest point of the cleaning process. After the water is filtered, it then returns to the pond, making sure the filter is the last thing the water reaches. As the water flows through the filter, foam cleans the water of organisms and matter.

Interestingly enough, the very microorganisms that you are seeking to filter are often stored in the foam of the filter so that the water is essentially being composted into food as it passes through the filter.

These filters have several advantages. For example, they are very easy to reach when you need to repair or replace them. Typically they are above ground, putting them very close within your reach. Some of them are even self-cleaning. Also, you will need to replace parts of the filter at times, so it’s best that they are close by.

Pressure Pumps

Pressure pumps are one of the bestselling kinds of OASE pond filters. As opposed to flow-throughs, which essentially allow the water to just flow through the filter, pressure filters force the water through the filter with the pressure of the pump. They are different from flow-through systems because they can be placed below the water level.

These pumps are typically considered the best option for any sort of pond that is placed high above ground. For example, they are very popular in links courses throughout the UK. The ponds can be placed on high ground in the undulating course. They can be buried so they do not form another hazard or disturb the look of the course. The disadvantage of these systems is, of course, that they are below ground or below the water level. That makes them slightly more difficult to repair or replace.

Your pond should be a centrepiece of your garden; it should draw you and your guests to relax next to it. However, no one wants to relax next to a smelly pond. To keep the pond from becoming smelly, you need to make sure that you filter the water regularly through clean filters. Your two basic options are flow-through filters and pressure filters. Flow-through filters are simpler and taller systems that are easy to replace. Pressure filters allow you to hide the filter, preserving the natural look of the pond.
