Re: Sticky Doc Bio Filter
This can be done, you will still go through some cycling but in most cases it's almost unnoticable, However, The filter needs to be kept running during the process, you can't turn it off do everything refill the pond and expect this, the bio will die off, in just a few hours, also cleaning the whole pond and starting the pond over you will not want to have a heavy fish load. You will need to declorinate the water and allow for ALL the chlorine/chlormine to break down before you start running the water back through the filter.
In my opinion, I would do a few large water changes and vacumn as much as possible off the bottom as you can each time, this will allow you to keep everything running, won't kill off the bacteria growing on the walls and such and still keep the pond running during the cleaning porcess.
