EHEIM Undergravel Filter

Two different undergravel filters, which work on either the reverse flow principle or the suction principle. 

Reverse flow principle:

The filtered water is drawn up through the gravel floor and the floating particles of dirt are then drawn into the inlet area of the filter.

Suction principle:

The suction principle works the opposite way round, operating like an additional panel filter. It is particularly suitable for salt water aquariums and tanks without plants
