I made it this year too!
Filtration device that works for free!
This item is recommended for those who do not have a power supply on the balcony!
Of course, there is no outlet on the balcony of my house.
If you use this device, you can supply oil film on the surface of the water and oxygen!
DIY after a long time. After all it is fun to think and make it yourself!
