How a Garden Pond Filter Works
We can get started by looking at how pond filters work. Basically, this sort of filter is designed to reduce the amount of potentially harmful bacteria that is floating around in the water.
In fact, it is important to point out early on that there are actually some different types of pond filter in use. Typically, all of the different types of function are now carried out in one device. However, this isn’t always the case and it is still good to understand the differences between different pond filtration systems.
First of all, a UV pond filter also know as a UV clarifier will kill off the green water, which will keep the pond nice and clear. Yet, this function isn’t enough on its own, as it won’t filter the dirt and rubbish from the pool.
This function is carried out by a biological filter. It is this element that keeps the water clean and healthy for your fish by introducing friendly bacteria that work to break down the bacteria in the water.
In some cases there is also a physical filter that acts as a barrier and picks up pieces of dirt. This needs to be changed or cleaned regularly to keep it working well and being effective.
Why You Need a Pond Filter
If you have fish in your pond then you will definitely want a filter, as this will give them a healthy place in which to swim and to live. It is also going to make the pond more attractive for other types of wildlife – such as birds and nocturnal creatures – to use.
If you aren’t going to put fish into the pond then you might simply want to use a filter to keep the water crystal clean and free of nasty bacteria. Of course, families with children might also worry about what would happen if the little ones spend time messing around in an unhealthy pond with no filter.
Those pond owners who decide to opt to not get a filter can look to maintain a natural balance in the water instead. This will do the same sort of job in keeping the water clear and healthy but it can take time to get a balanced nitrogen cycle in place.
Those who decide to go without a filter will need to have plants covering about two thirds of the water, to clear up the toxins. You should be able to introduce fish about a year and a half after starting up this type of balanced pool.
On the other hand, a biological filter will take up to around 6 weeks to have enough helpful bacteria to do its job.
How to Choose a Pond Filter
There are a few different factors to take into account when choosing the right filter for your pond. The starting point has to be with the capacity that you need, bearing in mind the volume of water and the number of fish in the water or whether you need a koi pond filter.
You will also have more need of a bigger capacity if your pond gets a lot of sunlight on it and has few plants in it. There is no risk of over-filtering with the biological filter, so it is better to be safe than sorry if you have a lot of fish that you want to look after as well as possible.
Most modern pond filters are very easy to set up, so you should look for one that you can have up and running without any hassle at all.
