Waterfall Pump Selection Using Oase Aquamax Eco Classic Control Pumps

oase aquarius control waterfall selector

To calculate which pump is required for a waterfall use the above graph. You need two measurements , the width of waterfall and the height of waterfall (height is vertically from top of water in pond to top of waterfall)

For example a 500mm wide waterfall which is 1000mm high, will need an Aquamax Eco Classic 9000 C pump.

To see what flow rate this pump gives at a paticular height use the graph below.
