Can I make a filter myself?
It is possible to make your own biological filter and we have high quality filter media such as Biomatt for this very purpose. When making your own filter consider the overall cost and extra time it will take to clean. If your time is valuable you’ll be better off buying a filter that’s had all the design work and low maintenance features built in.
Can I use my old swimming pool filter?
No. Swimming pool filters are not suitable for ponds. Pool filters are mechanical filters that are designed to catch small particles in the water. They do not perform biological filtration and are therefore not suitable in ponds. A pond filter will mechanically remove particles in the same way but also remove toxic waste through biological filtration.
Do I leave my filter on if I go away on holiday?Yes but check to see if it needs a clean before you go. Although if going away for an extended period please ask a friend, relative or pond maintenance specialist to check on the whole pond as well as the filter.
Do I need a filter?
If you want clean healthy water yes! You may know someone that tells you their pond is crystal clear and they don't have a filter but what they're not telling you is that they're regularly emptying and scrubbing their pond. A good working filter means you save water by not having to empty your pond and lets you have a good healthy environment for your fish. You wouldn't let your dog or cat live in their own waste so why do it to your fish?
Do I need power for my filter?
Only if you’re using a filter with a UV light.
Does the amount of fish make a difference to the type of filter I need?
Yes, the amount of fish in your pond will make a big difference to the size and type of filter you require. The more fish you keep the larger the filter you require. Always let your retailer know how many fish you have in your pond when selecting a filter.
How do I clean my filter?
High quality filters let you clean the filter without getting your hands wet but from time to time you'll need to give them a more thorough clean. You'll need to turn off your pump then open your filter and take out the media. The filter media should be cleaned with pond water or rain water only as the chlorine in tap water will kill much of the beneficial bacteria. Never use cleaning agents or bleach because this will kill your bacteria and then your fish when you turn your system back on.
How does a pond filter work?
Biological filtration performs a process known as the nitrogen cycle. In this cycle organic pollutants that enter the pond via fish waste, decomposed plant matter or excess fish food are converted from toxic to non-toxic substances using oxygen and bacteria. If the harmful substances are not broken down by oxygen and bacteria then algae is encourage to grow and fish kills can occur. The process is the same that occurs in aquariums, just on a larger scale.
How does my filter move the water?
It doesn't, you need a pump to do this. A pump moves water and filter cleans it, you need both to get clean water.
How long will my filter pads last?
Every pond is different and this will depend on your individual circumstance, although generally, you should get at least two years out of your filter sponges and replacements are available.
How many hours a day does my filter have to run?
A biological filter must run 24/7 to sustain the bacteria and oxygenate the water. This is why pond pumps with low power consumption are recommended for filtration systems.
How often do I have to clean my filter?
Every pond is different so there is no easy answer to this question. As a general rule you should clean your pump and check your filter when you notice a reduction in water flow on the outlet side of the filter. High quality filtration systems will have inbuilt mechanisms that will tell you when it’s time to clean them.
I want Koi in my pond, does this make a difference to the kind of filter I need?
Yes, Koi are a beautiful fish that can grow to a large size but also produce a lot more waste than other fish species. Koi ponds require high amounts of oxygen and larger filtration systems.
If I have a UV light do I need a filter?
Yes, a UV light does not perform any biological filtration and will not stop the build up of toxic substances in the way a biological filter will. The filter will also catch the dead algae that would otherwise turn into sludge at the bottom of the pond.
Is the bacteria in my filter harmful?
Not at all, it is a natural bacteria that occurs in all natural water systems.
The box in the shops says the filter will do a large pond but the filter itself is small, is that right?
Most filtration systems that are available in Australia & New Zealand are manufactured in Europe and the recommendations on the packaging are for European conditions. We have different environmental conditions and therefore most ratings found on filtration packaging will not hold true in our climate.
What is a skimmer filter?
A skimmer is designed to catch leaves before they fall to the pond floor where they break down and form an organic sludge that feeds algae. Skimmers can be attached to the suction side of a solids handling pump or be built in to the side wall of the pond during construction.
What is an internal filter?
An internal filter sits inside the pond underwater. They are usually attached to the suction side of the pump and are not as efficient as other styles of filtration as they are relatively small and have low oxygen availability for bacteria. Internal filters are used in small ponds up to around 1000 litres.
What should I consider when buying a filter?
Where you can locate it; How often do you want to clean it; How easy it is to clean; The amount and type of fish you have; The size of your pond; Will it do what it claims on the box.
What type of filter do I need for my pond?
Pond filters are known as biological filters as they purify water through a biological process driven by bacteria. Biological filters convert toxic substances that pollute the water, feed algae and can harm your fish, into non-toxic substances through a natural process known as the nitrogen cycle. There are many types of biological filters but all need to be sized according to the size of your pond and the type and amount of fish you wish to keep.
What type of filtration is best?
It depends on your individual situation and the size of the pond.
When should I think about a pond filter?
When you're planning your pond. If you think filtration when you're planning and constructing your pond you’ll have more choices available to you. We see many cases where customers need a certain type of filter but can't use it because they’ve already built their pond and there's nowhere for it to go. Even if you don't buy your filter right away at least plan for it in your construction so you can install one when required.
