Oase BioMaster 350 Thermo External Filter Heater Aquarium Fish Tank Filtration Media. Inc, pipework, acrylic tubing, spraybar etc. This model has an integrated heater, so no ugly heaters in the tank.The thermostat is easily adjusted while the filter is still running. The priming mechanism is a simple one push device and the pre-filter can be detached from the canister for easy cleaning allowing the main filter media to stay untouched while the filter is cycled. I have been in the hobby for over forty years and this is by far the best external canister filter I have come across.
