ADVANTAGES - Price (all with sand about PLN 45) - buying new items, because you can look for something at home. Simplicity. It works really well what I showed in the test movie • Domowy filtr piaskowy ...
FAULTS - You need to adjust the speed of pumping the water to the filter and the outflow. Setting the drain above the water level. The fiber and sand filter well and with time you have to clean the whole, rinse the fiber.
