      UV light & bacteria

      Can a UV clarifier(NOT sterilizer) kill both good & bad bacteria that's free-floating in the pond?
      I ask this because I just upgraded my DIY shower filter by adding another tub, and was wondering whether I should shut off my oversized UV light for a few weeks for beneficial bacteria to be able to colonize on the new media.

      What do people in colder climates(under 40F) do when their water warms up in the Spring? Will a filter never cycle with an active UV light?

      No. It will not harm good bacteria. I’ve been running a uv, and the past couple years a uv sterilizer, and my pond has cycled and stayed cycled just fine.

      It depends - a clarifier is going to reduce the population of all the free floating bacteria etc good and bad. If youre cycling your filter in theory it might slow that down a bit. Most importantly if you have added a bacterial formulation booster you would want to hold off until your bacterial population "settles" into you bio filter. Other than that what's said above is essentially correct.

      I just put the new tub on the bottom and the other media will quickly seed the new media.
