Can anyone advise me on how long it would take the canister (or more accurately the bacteria) to turn anaerobic and poisonous following any kind of power outage?
I've seen reports ranging from 1 hour to 12 hours in various places - does anyone know anything more accurate? or can speak from experience?
Would fitting a UV filter on the return pipe make this any less fatal for the fish?
btw I have a 30 gallon coldwater, plantless set up.
thanks in advance
