Additional Strenghts of the CHJ Pump Series are the especially quiet engines and the suitability for Fresh- and Sea Water.

The capacity of the aquarium pump must be necessarily adjusted to the size of the aquarium filter. Any oversized flow rate will result in an overflow of thefilter which is to be prevented at all costs. Moreover, you should take into account the aquarium´s circulation cycle as well as the period of time of the aquarium water in the filter.

According to the type of usage, the ideal circulation cycle depends on different factors: the fish population, aquatic plants or the desired water clarity. It goes without saying that, as the case may be, there are further components of the filter circuit that are to be coordinated, if necessary.
