Hi all.

Thinking about adding a uv sterilizer to my tank. The tank in question is still in the planning / construction phase, got the tank, its 650/700 Lts and going to be running a pair of Eheim 2217's. Its going to be stocked with African cichids and a few plants , the tempory tank the fish are currently in has algae problems and with out cutting back food even more and starving the fish was thinking about adding a uv sterilizer into the plumbing set up when i get that far, but have never had one and no idea about plumbing it into the return line of one of the Eheim canisters. Any recommendations or advice would be appreciated.


Regards Stewie17

All of the ones I've done I have mounted them inside my aquarium stand and plumbed them up via the flexible line going from the filter to the tank, that way the UV filter is not exposed to any particulate that may build up inside and reduce its efficiency. Its not difficult to do as most good units come with a reducing fitting on each side that you can cut to suit the different hose sizes. I usually add cable ties (as tight as I can get them) or proper hose clamps (not too tight as you'll break the plastic) just for a bit of peace of mind.


Remember to ask your LFS about the globe efficiency life, usually 9 to 12 months between replacements.

Connecting it into the return hose is pretty simple, some points to consider:


  • select a unit that can handle the flow of the canister
  • if you mount it on your stand, put it somewhere where it is easy to get to in case of emergency or maintenance
  • somewhere where in case of a tank leak, it doesn't get dripped on
  • leave it running 24/7 like your canister
  • make sure all hose connections are secured with hose clips or at least cable ties
