RE: [APD] dead bio-balls
I don't have a trickle filter, but I have had my turtle filter (canister) turned off for approx. 48 hours with no problems when it got air-locked and my husband unplugged it and forgot to tell me. I should note that there are ammonia absorbing chips and carbon in her filter. The planted tank filters have been okay after 24 hours. I should also note that this was in the winter with a house temp of approx. 72 degrees F, not in the middle of summer. I would think that as long as the bio-balls didn't dry out they'd be okay for a while. Someone correct me if I'm wrong, but I'm pretty sure that the bacteria goes dormant in the absence of food.
revance at indiana_edu asked:
Does anybody have an idea of how long a trickle filter can be turned off
before the bacteria will start to die off? I have a small pump running on a
UPS to help prevent this from happening in a power outage, but was just kind
of wondering "what if". We get some pretty big storms and toronadoes here at
this time of year, so there is a possibility that the power will go out for
longer than the UPS can last. I would hate for the bacteria to die off and
then foul up the water when it comes back on. I realize there are many
variables in this question... I am just looking for a rough estimate.
