And this thing also does not also affect its cleaning, is also easy to clean. The filter media we use are relatively speaking are resistant to water washing chlorine.
The keel structure.
This filter cotton is thicker then um resistance will be higher, but its volume is much higher.
The use of a longer period of time.
