The garden pond and its filtering: Today there is up Aquaristik.org an excursion to the garden pond builders and owners, because today we are devoting ourselves to them filtering a garden pond. As is well known, pond pumps are also used for this purpose. Not only pond pumps, but also abdominal pumps and Solar pond pumps Let's take a closer look here.

 

Do you even need a pond pump? What is the point of a pond pump?

This question cannot be answered universally. Ultimately, this depends on many factors away. For one, it depends on the size of the garden pond at. This size is usually given in m3. So the cubic meter capacity in liters. Then the pond pump manufacturers put how Ubbink, Oase, Velda, Heissner, SunSun, Pomtec, Gardena, Soelltec and more, also those Performance of the pump per hour.

A biotope in nature usually has a water inlet and a water outlet and thus new water and circulation is constantly carried out. This is usually not the case in our pond. The biotope should therefore be supplied with nutrients and co.

A smaller garden pond can sometimes do without an additional pump and filter. But when Pisces are kept in the pond, we always recommend a pond pump. This increases the safe and fast oxygen content and also ensures that the water is circulated accordingly. This also prevents the emergence of algae and mud. Standing water can tip over, especially in extreme heat and drought. This would endanger the life of the fish. In addition, it can also happen that the water in the garden pond starts to smell and stink. This is also a good sign that a filter and pump should be put in place.

Of course, the need for a pond pump also depends on the plants in the garden pond. Do you have enough plants in the water, then the oxygen supply pose no problem. Nevertheless, the circulation of the water is completely missing.

Whether one pond pump but may also depend on other factors. For example, this can have optical reasons. A beautiful stream or a fountain with a fountain also makes a lot. Water features liven up a garden pond. This is where you have to make use of the technology. Therefore, when planning a garden pond, it is important to consider how you want to equip it later. Here is an overview of the reasons.

 

 

Reasons for a pond pump

 

 

Which factors have to be considered when choosing the right pond pump?

If you have decided to equip the garden pond with a pond pump, then you first have to decide which pump is the right one for your pond. Factors play a role in this. For one is the Usage decisive. Be it for the stream or just for circulation. Or would you like to be able to integrate water features and fountains as well?

Another factor is the size of the garden pond and the associated flow rate of the pump. Depending on the manufacturer, there are different strengths and classes. But more on that below.

Of course you also have to pay attention to the costs and not only they play a role here acquisition cost a role, but also the consumption and maintenance costs. Especially that one power consumption can be crucial here. That's why it makes sense about one Solar pond pump to think more carefully. This is powered by solar energy.

The possibility of connecting to the pump can also be decisive. Here it depends on the diameter of the hose or on the connection systems used.

The cable length of the pump can also play a role. Where is the nearest socket or power supply for the pump and how do you control it.

In addition to the delivery rate mentioned above, the depth of the garden pond and the delivery height also play a role. The deeper a garden pond is and the higher the water has to be transported, the greater the performance must be. This is also a decisive factor for a stream.

The use of the garden pond is certainly also an important factor in the selection and purchase of the right pump. If this is also to be a swimming pond, then a different pump is required, as with a natural biotope.

 

 

What flow rate is required for a pond pump?

Let's now answer what flow rate you need for your pond so that it represents a balanced relationship. First you have to capacity know in liters. As already described above, this is given in cubic meters, because a specification in liters, as with the aquariums, makes little sense. According to this capacity then also depends output.

Many manufacturers provide tables for their pumps and suggest corresponding values ​​for where the respective pump can be used. You read about it again and again Formulathat the delivery line should be half the size of the capacity. Thus, the pond water could be completely circulated once in 2 hours. Going stubbornly according to these formulas makes little sense, because it also depends on the type and use of the garden pond.

If you go by this formula, the flow rate for a 10.000 liter pond (10m3) would be around 5000 liters per hour, so that the water can be completely circulated in two hours. The performance of many of the pumps can also be throttled and adjusted accordingly.

In addition to the delivery rate, you should definitely pay attention to the second value when it comes to the head the pond pump is working. On the one hand, the choice of location for the pump also plays an important role. It makes a difference whether this sits at the bottom of the 2 meter deep pond or in a shallow water zone. In addition, it is also crucial, for example in the case of a stream, how long it should be and what the difference in height of the water is. You have to pay attention to this and select the appropriate service.

 

 

What types of pond pumps are there?

Now we come to the different types of pond pumps. These can be classified as follows. Pumps with filter options, stream pumps, fountain pumps, pure circulation pumps, solar pond pumps and also special swimming pond pumps.

 

Pure circulation pumps

Certainly the most widespread pump is the pure circulation pump. This does not make high demands in terms of technology and ultimately only has to be considered Delivery rate and delivery height become. Filtering is usually not provided here, but you could build it yourself. To do this, only the sucked water would have to be passed through appropriate filter media. The principle of operation is quite simple. In the motor, which are mostly centrifugal pumps, there is a magnetic drive which drives a delivery rate. This ensures that water is drawn in on one side of the connection and the water is released on the other side. Thus the water is circulated. The placement is freely selectable, but should still be in the deeper area of ​​the pond.

 

 

Pond pump with filtration

Of course there is pond pumps, which filter media, such as filter baskets, also have with them. These not only circulate the water but also create a filter. suspended solids are thus filtered out of the water and this usually makes it much clearer. Of course, these filter media also have to be cleaned again and again. Here the pond pump is combined with the filter pump. We recommend this type of pond pump, especially for garden ponds with fish. With a koi pond, for example, you cannot do without filtering.

 

 

Solar pond pump

Basically, this type of pond pump is the same as the circulation pumps and filter pumps. The main difference here lies in the Energy supply the pump. No mains supply with 230 volts is necessary here. The operation takes place purely with the energy of the Sun, which of course has many advantages, but also disadvantages. Be it the saving of energy costs or the ecological use. Unfortunately, you also have your problems if the sunlight is not available for several days.

 

 

Water feature and fountains or fountain pumps

Everyone knows the beautiful fountains, be it in the room as an indoor fountain, or in the home garden. Public facilities often have these wells and special pumps are used there, which have to be designed larger, especially in terms of performance. A water feature can also be a real eye-catcher in your garden pond at home. Filtering plays a subordinate role here.

 

swimming pond pumps

If you also want to swim in your garden pond, you should not only make it large enough, but also make sure that you use the right technology. Here you not only usually need a higher performance, but also different connections to ensure a complete circulation of the water. In addition, the water here should also be particularly clear. The operating mode is also decisive swimming pond pump. Especially in smaller ponds, models that are operated with 12 volts are used. So you only have low voltage in the garden pond and you are on the safe side when it comes to safety.

 

 

How much does a pond pump cost?

It starts with just a few euros for the mini pond with just a few liters (less than 1000 liters). As always, there are no upper limits here. This usually depends on the design and drive type and of course also on the pumping capacity of the pond pump. The manufacturers also differ very often in terms of price. You should also pay attention to the possibility of obtaining spare parts. You should also consider warranties and guarantees. Regulations and controls for garden pond pumps are also very important and should be considered in the functions.

 

 

How does the filtering of the pond pump work?

There are basically different types of filtering here. A distinction is made between the usual filtering, which is usually only sufficient for small garden ponds and fountains underwater filtering. Here only a few filter media are installed upstream of the pump to remove dirt from it so that the engine is not damaged. We would not be talking about real filtering here.

In the pressure filters, even larger ponds can be operated, whereby the filtering is also more in the background here. In most cases, it is about the forwarding of the water into the stream or to the water feature.

In the pass-through filters one can already speak of a very good filter performance. These are usually quite large and sit outside the garden pond. There the water is passed through slowly so that an optimal filter effect is created. Most of these can be done Filter systems expand modularly. Here one speaks then also often of module filters.

In the case of the smaller filters, the pump is usually already integrated in the system, with the pump being located downstream in the larger systems and directing the water through the corresponding filter baskets.

 

Algae in the garden pond

Unfortunately, there is not only in Aquarium algae, but they also occur in the garden pond. The basics in particular can often be found in garden ponds. Be it the thread algae or the floating algae. Surely one or the other has already heard about the algae breeding. In order to prevent this, it makes perfect sense to purchase a pond filter or a pond pump. It can even go so far that a UV clarifier could also make sense.

We therefore recommend filtering the garden pond right from the start and during the planning phase. This is the only way to enjoy your biotope in the garden for a long time.
