A garden pond represents its own small biotope. Numerous plants thrive here, both on the bank and in the water. The latter sometimes include unwelcome algae that reduce the water quality in the long term, don't look particularly nice and can even be dangerous for fish. Do you still have an unused water butt? Perfect, then use the following instructions to build an effective pond filter.
With five rain barrels, water can be filtered well
Required material
- 5 rain barrels
- a pump
- around 15-20 brushes
- one fine and one coarse filter mat each
- a UVC lamp (alternatively, a classic lamp is also possible)
- Pipes (4 connectors, 10 pipes at 90° angles, 10 pipes in a straight line, and 5 additional pipes)
- 10 rubber passages
- granules
building instructions
In this building guide, your water will go through five different purification cycles:
- 1. Ton: Light purification and whirlpool
- 2nd bin: brushes
- 3rd bin: Granules
- 4th bin: coarse filter mats
- 5th bin: fine filter mats
The barrels are connected accordingly. To make assembly easier, it is advisable to install the connecting pipes later. This gives you more mobility.
- Drill holes in each bin about 4 cm below the top edge.
- Attach the rubber seals to the pipe connections.
- Place a pipe vertically in the first bin.
- The end meets the edge directly, so that the escaping water later starts to rotate.
- Put the UVC lamp in the bin.
- Also put a pipe in the second barrel.
- However, this points vertically downwards.
- In addition, install the brushes.
- Fill the granules and an air bubble stone into the third barrel.
- Fill the last two bins with the coarse or fine filter mats.
- In the last step you install a pump in front of the filter system.
- Now you can start a test run.
