    Our most frequently asked questions on bead filter.

    How Much Filtration Do I Need For My Pond?

    The level of filtration that you need for your pond depends on the size of your pond and the number of fish in the pond.

    Note that filters are rated to the volume of water in the pond. Nevertheless, a pond with fish will require more filtration than one without fish because of the waste and crumbs of the fish inside the pond.

    Therefore, you should acquire a filtration system that is 2x the filtration capacity of your pond. For instance, if your pond has a 2000-gallon capacity, you should get a filtration system that has a 4000 capacity.

    What Are The Benefits Of Using A Bead Filter?

    Also known as pressurized filters, bead filters can be mounted at or below ground level. Also, they can process vast volumes of water.

    Besides, the water flows slowly into bead filters, which provides better filtration.

    What Are The Differences Between A Pressurized And Non-pressurized Filter?

    Both the pressurized and non-pressurized filters do a great job of filtering the water system in your pond. However, these two differ and have their perks and setbacks.

    To start with, pressurized filters or bead filters are quite challenging to install compared to non-pressurized filters. But when it comes to designing the pond, the bead filters provide you with more flexibility than non-pressurized filters.

    Additionally, bead filters can filter large volumes of water compared to non-pressurized filters.

    However, water moves slowly, which can lead to oxygen depletion, and it can negatively impact your biological filtration. Last but not least, bead filters are slightly more expensive than non-pressurized filters.

    What Size Of Pump Do I Need With My Koi Filter?

    It is highly recommended to acquire a large filter that can handle all the water in your koi pond every hour.

    For instance, if you have a 2000-capacity pond, you should utilize a 2000-capacity pump or larger than that. Getting a bigger pump is always better.

    But if you have a bead filter, you should ensure that you use the right pump as the pump’s flow rate will have an impact on the pressure in the filtration system.

    After What Period Should I Clean My Bead Filter?

    There is no specified time for cleaning your bead filter. However, you should keep an eye on the outflow from the system.

    Also, having a bead filter is advantageous as you don’t have to worry about running past the required cleaning time. All you have to do is backflowing the bead filter from time to time.

    Final Thoughts

    Now that you know what the best bead filters are, you should get a pressurized filter that meets your needs.

    Different people have different demands, so we’ve included different bead filters to suit all of you.

    A koi filtration system is as important as the food you feed the koi. So, get the best bead filtration system for your pond so that you don’t have to worry about clean water anymore.

    Also, the right bead filter will ensure that water flows smoothly and the chemistry in the pond is properly balanced for your koi fish to live healthy and joyful.

    Take your time and go through the pros and cons before choosing. All the best as you select the next koi bead filter for your beautiful koi pond!
