Features & Benefits:

This filter allows you to have less equipment in your tank - by retrofitting a heater takes the heater from unsightly in the that tank to well hidden and out of the way. No fish burns or fish breaking the heater. The prefilter makes cleaning a breeze without having to dismantle the whole canister to do a clean.

  • Optimum filtration: Fine 45 ppi pre-filter sponge to optimise mechanical filtration of coarse dirt and prolong the lifespan of biological media
  • EasyClean prefilter module: No more bothersome dismantling of the filter – simply remove the pre-filter module, rinse and replace
  • High filter volume: The combination of mechanical and highly effective biological filtration with Hel-X ensures healthy and clear aquarium water
  • Practical: Venting button for effective water suction to get started quickly and easily during installation and after cleaning
  • Safe: Shut-off mechanism and safety lock prevent unwanted water leakage, e.g. when removing the pre-filter module
