Product Spotlight: Bermuda Pressure Filters

Any pond, if you want it to look clean and clear, requires some kind of filtration. There are many different styles of pond filters, however, one of the most common and reliable is the pressure filter. Pressure filters sit outside the pond and are powered by a pump. The pump generally will sit in the pond and push water through the filter via tubing. Water then flows back into the pond from the return line, which may be just a hose, a fountain, or even a waterfall feature. Since these filters are pressurized, it
makes them an excellent choice for ponds with waterfalls, ponds that are up slope, or for ponds where a suitable location for your filter may not be nearby. They do not need to be elevated higher than everything else, like a gravity filter (non-pressurized) would require.

Pressure Filters provide mechanical and biological filtration, as well as, in some models, ultraviolet clarification. As dirty water from the pond flows into the filter, it passes through the chamber housing the ultraviolet light. This process sterilizes the water, subsequently killing the algae responsible for turning your water green. Foam pads inside the canister then collect the fine debris and fish waste produced from your pond, providing thorough, mechanical filtration. Pressure filters will normally come with biological media as well… these are the best kinds! You’ll normally see bio media in the form of plastic balls, ceramic pellets, or lava rock (very lightweight, porous stones). This offers beneficial bacteria a location to colonize within your pond’s ecosystem. Biological filtration is important in balancing your pond’s water chemistry. Fish’s waste, if not broken down by beneficial bacteria, will cause ammonia levels in the water to rise, potentially harming, or even killing, your fish! This final step in the filtering process
ensures your water will not only look crystal clear, but be kept healthier for your fish as well.

As the filter does its job collecting pond debris and dirt, eventually the pads will need to be cleaned so the filter can keep running effectively. If you notice a slower flow rate coming from your return line, or the pond is becoming dirtier more quickly, then that is a good indication that your filter may be becoming clogged, and should be cleaned more frequently. If you find that the filter needs to be cleaned very often, it is most likely
that your filtration system is undersized for your pond and/or fish load.

When it comes time to clean the filter, there are two ways to do it, depending on the brand/model. For some, you will have to physically open the filter and remove the foam pads, then wring out the pads and place them back in. Many newer filters will have what is known as a “backwash” feature. Pressure filters that can be backwashed do not require you to take the pads out… or even get your hands dirty! These types of filters will have
some kind of internal mechanism that will physically scrape or squeeze the pads simply by pulling a handle or turning a lever on the outside of the filter. As this loosens and frees dirt and debris from the pads, the flow of water is switched from the return (normal operation) to the discharge (backwash mode). This makes sure none of that dirt goes back to the pond and is pumped directly out of the filter. Once the water runs clear, simply switch the flow direction back to the return, and you’re done!

Tip: ALWAYS turn off your pump before switching flow direction on the filter. Switching flow direction while the pump is running can cause damage to your filter, regardless of the manufacturer. And don’t forget, dirty pond water and sludge make excellent fertilizer for gardens!
So how do you pick the correct size filter for your pond? When purchasing a filter, keep these details in mind: Filters are often advertised with what size of a pond they are good for. But this is actually the rating for when there is minimal sunlight hitting the pond, and no fish. In reality, sunlight will almost always be a factor, and the vast majority of pond owners want fish!

As a general rule of thumb, whatever size pond the filter is rated for, cut it in half. For example, if the filter claims it is good for ponds up to 2,000 gallons, any experienced pond supplier will tell you that wouldn’t be sufficient enough for a pond more than around 1,000-1,200 gallons. There is no harm in fitting your pond with a filtration system that is larger than you need, however. This will actually allow you to add more fish to the pond, as you now are supplying more biological filtration. Be mindful of what size pump you plan to use as well. Each filter will
have a recommended flow rate. If the water pushes through too quickly, you risk damaging the filter from the pressure.
