    How long can benifical Bacteria survive without water? I am asking this question because there will be an hour (maximum)while cleaning my biofilter the media will not be submerged. The media is k1

    The bacteria should survive for an hour with no problem. My question is- Why would it take an hour to flush a biofilter?

    First thanks for the response
    I didn't clarify but this is not for a pond biofilter . I am am adding k1 to a sump for my 125 gal discus tank. I clean the sump once a month by removing all the water. I have matala pads in the sump that I swish around to knock the muck off and then put tem into a plastic container with tank water. While the main tank is refilling I put the matala pads back into the sump. . The k1 will be partioned off and will be without water during this process. Usually takes me 30 -45 minutes start to finish.
    I put the question out here because pond or fish tank the bacteria is the same. I was hoping to get a response from you.

    An hour is just a conservative relatively safe estimate. The age (maturity) of the biofilm on the media along with the fish load in the tank will also affect the amount of time. Of concern is not just the Oxygen supply to the bacteria but also the sudden absence of any Ammonia and Nitrite which the bacteria and possibly Archaea need to survive and grow. Less damage will occur to a well-developed biofilm than one that is recently formed.

    Just as every pond is different so is the composition of the bacterial/archaeal communities that populate not only the biofilter but the pond itself.
