Globally, energy stats aren’t so promising nowadays. Even if there’s an abundance of electricity, why not have an energy-saving filter if you can?
You might want to save money or go off-grid, but regardless of the reason, it’s an idea worth trying.
The engineers have already laid the laws clearly. So, all we need to do is to find out-of-the-box means for applying them.
In this article, we’ll explain how to make a pond filter without electricity. We’ll also touch upon other creative ideas for filtering water.
As long as you’re concerned about preventing algae growth, you can fight nature with nature. Simply put, you’ll add other living beings to the pond, to hamper algae growth.
Here are two of the most common natural filtering options.
Underwater animals that feast on algae will balance your pond’s ecosystem. You can go for snails or shrimp.
Similarly, you can host fish species that are famous for cleaning ponds, such as mosquitofish, goldfish, and Siamese algae eaters.
Aquaponic enthusiasts would encourage you to rely on plants for filtering your pond. Not only do they create more visual interest in the water, but they also contribute to a healthier environment for your fish.
The plants would absorb carbon dioxide, ammonia, and nitrates. In return, your fish will thrive on the oxygen that the plants release in the water.
Some of the most popular plants for aquariums and ponds include:
- Water Wisteria
- Marimo Balls
- Amazon Sword
- Water lettuce
The waste from the animals and fish in the pond will also provide nutrients for the plants. So, there’s no need to use fertilizers.
Fighting algae isn’t the only reason you need a filter for your pond. It’s crucial to maintain oxygen levels in your pond.
Otherwise, if oxygen levels drop severely, you might face unexpected fish kills. Besides the plants we mentioned earlier, there are a few other options that can aerate your pond without electricity.
If you’re only concerned about clean energy, you can go for solar panels or windmills. These systems can cause enough water movement on the surface, thus dissolving oxygen in the pond.
Still, you’ll need to have abundant sunlight at your place to get a consistent energy supply. For windmills, you’ll need wind speeds of at least three to five miles per hour to get enough energy.
If you’ve got a small pond, you can regularly replace a portion of the older water with fresh, aerated water. Depending on the size of your pond, you can change 25 percent of the water at two-week or one-month intervals.
Make sure the added water is chlorine-free, to avoid harming the fish.
This option doesn’t require energy, but you’ll need some muscular effort. Use a hand pump to move the water through a mechanical filter. This wouldn’t be an ongoing system, though, so you’ll have to repeat the process several times per day.
There are various ways of making your own filter. Here’s a simple way of crafting a pond filter without electricity.
For this smart mechanical filter, you’ll need the following tools.
- Three hoses
- Small valve controls
- A strong adhesive
- Three buckets
- Coarse gravel, sand, and charcoal
- Filter material
- Cutting tools
You’ll also need a heat source to make the holes in the plastic. This can be a stovetop or a simple lighter.
Heat a sharp metal tool like a crafting cutter or a knife. Then, use it to puncture the holes in the plastic of the buckets.
You’ll need to make the holes wide enough to fit the valve controls and the hoses. This system relies on pressure differences. So, everything needs to fit tightly, or else the water won’t flow.
You’ll need two holes on the lid of the bottom bucket, one hole on the top bucket’s lid, and another hole on its side.
Layer sand, charcoal, and gravel inside the first bucket. Then cut the filter material to the container’s shape and place it at the top.
Place two valve controls in the holes of the bottom bucket’s lid. Next, place the third valve control in the lid of the top bucket.
Then, using a short hose, connect the bottle’s side hole to one of the valve controls on the container’s lid.
Finally, connect the other two hoses to the control valves and place their ends in the pond.
To start the water flow, you’ll need to fill up the top bucket with water before you open the valves. After that, you can suck some water through the hose of the top bucket.
Clean water should start flowing from the top bucket, and the water in the pond should move through the filtering bucket below.
Even if your pond hasn’t got any fish, you’ll need to filter out accumulated waste from withering plants and nearby lawn runoff. We’ve explained how to make a pond filter without electricity to tackle this challenge regardless of energy availability.
In truth, the task is simple. As long as you understand the basic mechanisms of filtration and aeration, you can come up with numerous solutions.
Still, you might need some time to craft the system that works best for your fish. In the end, having a natural pond to rest around is worth all the effort.
