What is the best filtration system for koi ponds?
The more high-tech version of the Oase BioSmart is Oase’s newer BioTec filtration range. These fancy filtration systems provide some of the best biological and mechanical filtration for koi ponds on the market, and their unique “screening” feature hugely reduces clogging and overall maintenance.#N#Water entering the intake of the filter goes through an initial screening process before it can enter the main chamber with biological filter media. Debris collected during the screening process is automatically deposited in a separate holding tray via a rotating conveyor belt on a 30 minute process loop. This high-tech feature may seem like a novelty at first glance, but it actually provides really efficient mechanical filtration and prevents debris from entering your bio chamber which can clog bacteria and lower oxygen content. The screening system has a good width and would work great for all sizes of ponds, depositing debris every 30 minutes and letting your beneficial bacteria work uninterrupted.

What is a non-pressurized pond filter?
Non-pressurized filters are another option, being able to provide both good biological and mechanical filtration with little loss in water pressure. Although you’re more limited in terms of installation, quality box filters do not suffer from the same filtration issues as many pressurized ones. Water flow from your pond pump is not reduced when entering a box filter, so beneficial bacteria living on your bio-media will have much more oxygen content to help them process waste. The increased movement within the filter box also helps clean bio-media naturally, as the rapid flow literally knocks dead bacteria off so healthy bacteria can continue to colonize.
Why use a pressurized filter for koi ponds?
Pressurized filters are a popular choice in many pond builds, as the pressurized nature allows installation at or below ground level , providing more flexibility when designing your water garden. Water which flows through a pressurized filter will be much slower in comparison to a regular filter, and this can be both a positive and negative aspect for koi ponds. The benefit of the slower water movement means the filter media has more time to process water, with mechanical media collecting more debris and bio media removing harmful substances. The drawback of this slower flow rate is although it is often better for mechanical filtration, it biological beneficial bacteria can suffer under the slower moving conditions. This is because beneficial bacteria are aerobic in nature, meaning they need large amounts of dissolved oxygen to process waste. Water which moves slowly will carry less oxygen content, and depending on your ponds bio-load, could mean you’re not getting sufficient biological filtration.
How often should I filter koi pond water?

Non-pressurized filters will have minimal effect on water pressure, but if you have a pressurized filter you’ll need to take into account the reduction in flow rate as water enters the system. You can easily blow a pressurized filter if your pump is too strong, so you’ll want to double check a filter’s requirements before investing further.
