Calculate optimal pond filter performance - Calculate Now
The pond filter is an often controversial topic, which always divides the spirits. Some garden pond enthusiasts swear by a filter in the garden pond. Others invoke the natural ways and means that every body of water in the world makes use of. The idea that a pond filter is not necessarily necessary is, of course, not entirely unfounded. After all, even every natural pond can do without an elaborate and costly filtration system.
Why is a pond filter needed?
Whether or not a garden pond filter is really necessary, or even useful, depends first and foremost on what species of fish it is intended to house and how large and deep the pond at hand is. Then one's own aesthetic ideas play an immensely important role. This is because, especially in small ponds, the unfiltered water quickly becomes unclear and "unclean".
Most fish species don't mind polluted and algae-filled water too much. After all, natural pollution doesn't always have to be bad for the pond's nutrient content. Of course, it's a different story when it comes to appearance. The filter is primarily there to keep the water clean and clear. So that you can see your fish and your pond bottom without any problems or restrictions.
Pump or no pump - the question of questions
A pond filter usually consists of a pump and a filtration system. The pump is almost always indispensable, because it is often the only way to get the pond water moving - and only moving water ultimately gets you clean. However, a pond filter does not necessarily have to consist of modern and expensive complete systems. With a little know-how, you can also build a pond filter yourself in just a few steps. All you need is a suitable pump and a "filter system". For the pump, it is important that it is powerful enough. With the filter system, on the other hand, you can use different models from nature. The best examples of this are a small stream or a clarifier system. By the way, there are numerous instructions for DIY on the Internet.
Internal or external filters: well-known and popular types of pond filters
When it comes to pond filters, there are big and small differences. These are primarily found in the type of filter system. First, there is the shore filter, where the water is filtered outside the pond. The advantage is that a shore pond filter has a great performance capacity. The disadvantage, however, is that many garden pond enthusiasts find the outside pond filter visually unappealing. The situation is similar with the pond chamber filter and also the pond pressure filter, both of which are also installed outside the pond. The advantage, however, is that these types of filters filter very thoroughly. The only "invisible" filter is the pond internal filter. However, it is not only very unobtrusive, but also inexpensive. However, it is not as powerful or as thorough as an external filter.
How is the pond filter cost calculated?
How expensive a high-quality pond filter is always depends on three serious factors: how large is the pond in question, how powerful should the system be and what type of filter system is desired? In addition, it always depends on whether you want to build the filter yourself - or whether you prefer to rely on a complete system. Especially the costs for the latter can quickly amount to several hundred euros, depending on how powerful it should be. The cost of a self-built filter system can even be less than 100 euros.
Pond filter tips when buying
If you do not dare to build your own filter system, you should rather buy an inexpensive but suitable complete filter system. Otherwise, a self-built pond filter can not only save money. You can also adapt it much better to the size and requirements of your own garden pond. But: Either way, the filter system used should always be strong enough to cope with the present and thus also necessary water volumes. A somewhat stronger filter is therefore usually better than one that is too weak - as long as you value water that is always crystal clear.
Pond filter market DIY, build your own pond filter
More and more garden owners are planning to build a pond. A pond is a visual eye-catcher for the garden and creates a cozy and natural atmosphere to feel good. Whether it is an ornamental pond, a fish pond or a swimming pond, each type of pond requires appropriate care to remain usable and intact as an ecosystem in the long term. An important component is an efficient pond filter, which ensures that pollutants are filtered out of the water and that oxygen levels are always high enough for plants and fish to thrive in the pond.
Function of a pond filter
Pond filters come in different varieties, all of which are designed to ensure that the water in the pond stays clear and the water quality remains good. Fish excretions and dead plant debris deprive the water of oxygen. Therefore, it needs to be cleaned with a filtration system. When building or purchasing a pond filter, it is important to consider which substances are to be filtered out of the water and to what extent. A fish pond, for example, places higher demands on a pond filter than an ornamental pond or a swimming pond. The size of the pond also plays a role, because the more water there is to filter, the more powerful the pond filter and pump must be.
Compare pond filter types
Basically, four types of pond filters can be distinguished, which are suitable for all pond types and sizes. The underwater filter is installed before the pump and is particularly suitable for plant ponds and smaller ponds. However, its cleaning is somewhat cumbersome.
Unlike the underwater filter, the gravity system is located outside the pond. It is embedded in the ground next to the pond. The pond water enters the filter by means of wall or floor passages. After cleaning, a pump returns the water to the pond. A gravity system provides good filtration results and is therefore suitable for fish ponds, even those with demanding fish such as koi.
Pump-fed filters are placed at the edge of the pond. A pump at the lowest point of the pond carries dirty water to the filter. Pump-fed filters are the right choice for combination ponds. The barrel filter pumps water through several stages of purification, first trapping coarse dirt particles and then using granules to filter pollutants from the water. You can also build a barrel filter yourself with a little craftsmanship and the right materials.
Materials and costs for self-made barrel filters
To build a barrel filter for the garden pond, you will need the following materials: Five plastic rain barrels, each with a capacity of 200 liters. In addition, HT pipes in straight form and as elbows are required, as well as rubber seals, fine and coarse felt mats and brushes, furthermore granulate in the form of basalt, lava stones or gravel. The financial outlay for these materials is comparatively low and is likely to be between 50 and not much over 100 euros.
The biggest variable factor is likely to be the type and quality of the granules. The following construction instructions are designed for a barrel filter with a filter volume of 1,000 liters. With a powerful pump, the filter is suitable for a pond volume between 10,000 and 20,000 liters.
Building instructions for a barrel filter for the garden pond.
The principle of the barrel filter is based on the fact that the water passes through 5 stages and is gradually cleaned in them. In this case, the rain barrels represent the individual stages through which the water passes from the top to the bottom and finally from the lowest barrel back into the pond.
The 5 barrels are connected to each other with HT pipes. Cutouts the size of the pipe diameter are cut into each barrel below the rim. Seal the openings with a rubber ring and push the pipe pieces through. Inside the barrel, the pipe is extended with an elbow. The barrels are placed at a distance of about 5 centimeters from each other, ideally on a slight slope, and the first barrel is connected to the pump via a hose connection. Once the 5 barrels have been prepared in this way, they can be filled.
The first barrel remains empty. It is only used to get the water moving, which means that coarse dirt is already deposited. In the second barrel, the brushes are placed so that they stand vertically inside and can catch coarse dirt. The third barrel is filled with filter mats. They are also placed vertically inside. The mats can catch finer particles. Finally, the fourth garbage can is filled with granules, which can be basalt, lava or gravel. The stones should have a diameter of one to two centimeters. The granules are able to bind pollutants from the water. Finally, filter mats are again filled into the fifth barrel. Already the self-made pond filter is ready and ready for use.
