Dymax Power Head Pump - 1800PH

The Dymax Power Head Pump is a range of submersible power heads for circulation, running filters, fountains and sump returns, from PH200 up to PH5000.

Key Features

• Submersible, fully sealed motor for freshwater and marine use
• Eight models; the number in each name is its rated flow in litres per hour (e.g. PH1800 ≈ 1,800 L/h)
• Works as a circulation pump, filter pump or return pump

Choosing A Size

• For general circulation, aim for a turnover of roughly 5–10 times the tank volume per hour; reef tanks often want more.
• Rated flow falls as the pump pushes water higher — choose a bigger model for sump returns.

Available in: PH200, PH400, PH600, PH800, PH1200, PH1800, PH2500 and PH5000

Good To Know

• Never run a pump dry — it must be fully submerged before it is switched on.
• Clean the impeller and intake every month or two; debris cuts flow and wears the pump.
• Unplug all equipment in the tank before putting your hands in the water.
• Leave a drip loop in every power cable, so water running down the cord drips off before it reaches the socket.
• Plug aquarium equipment into a socket protected by an RCD (earth-leakage breaker).
