        Get Started

        Koi 101

        Koi fishes are the ones we commonly see in garden ponds. Did you know that more and more people are starting to take good care and even breed them not only because of their certain beauty but because they believe that it can actually give them luck?

        For example, if you want success in business, the metallic koi is for you. If you want wealth and prosperity, go for the gold one. If you like serenity, take care of a blue koi

        Koi Pond Maintenance

        The first thing that you must always make sure of when you have a koi pond is preventing it from getting overstocked with fishes. To calculate, there should be only 1 koi fish for every 10 square feet of surface area.

        The most important element to focus on is actually the quality of water. It can either make your fishes healthy or it can kill them. Water pollution and abnormal acidity can lead to different adverse effects. This is where your koi pond filter system will come handy.

        Things to Consider when Buying the Best Koi Pond Filter System

        A filtration system will be your initial step to sanitize your pond. There are plants and other marine lives that naturally filter your water but a filtration system makes the work faster.

        Filtration configuration

        There are three types of configurations in where pond designs are based. There is an external pond filtration which is used in koi ponds. This is specially made for fish ponds. This is the most flexible type as well. The water is drawn by a pump through an elevated chambered filter to a waterfall. This will then pour the water back down to your pond.

        The other two types are submersible pond filtration and the skimmer or waterfall external pond filtration. The latter is ideal for medium to large fish ponds as well. The next time you see a beautiful landscaping with waterfall effects, you now relate it to this kind of configuration.​


        Koi ponds are so fun and relaxing. It entertains people from all ages but if it is dirty, it will definitely make the spectators feel disgusted. We are so lucky because we now have tools to help us maintain the cleanliness of our water gardens.

        The best koi pond system I would recommend is Goplus Pond Pressure Bio Filter. It has a superb quality but you do not have to shell out too much money. It can tolerate old fish ponds and ponds with normal to heavy fish load without any trouble. It makes use of built-in bulb systems, pressure filters, and UVC ultraviolet purifier that makes your cleaning more efficient.

        The handle is ergonomically designed and the unit is also very easy to install. Many users have vouched for visible improvement in their pond water within days! You would not also look for additional hoses because it comes with adapters that can fit in different sizes.
