In the field of aquarium maintenance, how to keep the pond clear and maintain ecological balance has always been the focus of enthusiasts. Especially for those ponds far away from the house and without access to electricity, the choice of filtration system is even more challenging. Today, we will share a case of upgrading a non-filtered goldfish pond – installing a Poposoap solar pond filter for it, and see how this innovative device can bring new vitality to the pond ecology.
Pond Status and Upgrade Opportunities

About a year ago, we visited this place called "non-filtered goldfish pond." At that time, we thoroughly cleaned the pond, making it look brand new, and the fish lived very healthily in it. However, over time, the water in the pond began to turn green again. So, today, nearly a year later, we came here again, not only to carry out another cleaning work, but also to try to install a Poposoap solar pond filter.
In fact, this pond had previously installed a solar pond filter, but the effect was not good and it failed to effectively solve the problem of the green water in the pond. So, we are looking forward to this new equipment, hoping to improve the water quality and ecological environment of the pond through it.
Poposoap Solar Pond Filter Unboxing and Analysis

Some friends may be unfamiliar with the brand Poposoap. It is an emerging brand that mainly provides more affordable kits. Now, let's unpack this filter and see what's inside.
The first thing you see is a simple filter box. The top is the mechanical filtration part, which can intercept large particles of impurities in the water; the bio-balls are placed below, which are used for biological filtration, cultivating beneficial bacteria, and decomposing harmful substances in the water. In addition, there are fountain kits and water pumps. We plan to put the bio-balls at the bottom of the filter box, and it looks like there is room to add more.
There are also some tubings in the package (tubing here refers to water pipes), which can be adjusted in length as needed. The core component we are really concerned about is the solar panel, and we will test its performance today.
Installation Process and Details Considerations

Before installing the filter, we cleaned the pond and trimmed some plants appropriately, but did not do a lot of pruning, because this pond basically only needs to be taken care of once a year and has a certain degree of self-sustaining ability.
Next comes the crucial step of installing the filter. We used a zip tie to secure the filter to the top of a container. This container is a great design with lots of holes and small spaces that are perfect for fish to hide in. Remember, this is a natural pond and there are likely to be predators such as herons visiting, so this design gives the fish a place to hide.
The reason we didn’t put the filter directly on the bottom of the pond is that the pump is not very powerful and if it is placed on the bottom, it will easily get clogged by debris at the bottom. The purpose of installing this filter is not only to filter the water quality, but also to increase oxygen and possibly help drive away the herons.
Solar Panel Placement and Testing

After cleaning the pond, we will place the solar panel. Today is a good day with clear weather and plenty of sunshine. We put the solar panel in the right place so that it can receive as much sunlight as possible. The position of the sun will move, so we chose a place where the solar panel can receive more light throughout the day.
When the water level reaches the right height, we can turn on the pump for testing. From the test results, the performance of the solar panel is good. When there is sufficient sunlight, the water flow of the water pump is relatively strong; if you block the sunlight with your hands, the water flow will become weak. This fully reflects the characteristics of solar energy equipment. The more sunlight there is, the more power the system has.
Effects After Installation and Ecological Improvement

After some efforts, the Poposoap solar pond filter was finally installed and put into use. For this pond far away from the house and without electricity access, this solar filtration system is simply a perfect solution.
Now, the fish will live more comfortably in the pond. The water flow movement brought by the filter can not only purify the water quality, but also add oxygen to the water body, so that the entire pond ecosystem is improved. Moreover, the gurgling sound of the water can add a natural beauty to the pond, allowing the owner of the pond to enjoy this wonderful sound all day long.
Summary and Outlook
This attempt to upgrade the unfiltered goldfish pond with the Poposoap solar pond filter was very successful. It not only solves the problem that the pond is far away from the power supply and cannot use traditional filtration equipment, but also plays a positive role in improving water quality and enhancing the ecological environment.
As the weather gets warmer, we look forward to bringing you more articles on pond care and aquarium equipment use. I believe that with the help of this solar pond filter, this goldfish pond will always be in good condition and become a small ecosystem full of vitality and vigor. If you have similar pond care needs, you might consider this solar filtration solution, which may bring you unexpected results.
