Hey there i need some help regarding auto switching of 2 airpumps for my fish tank, i.e. only one airpump is given power and both are connected in parallel, with only one air pump working at one given point of time, now at the time when one of the pumps stop working, i want the other pump to start automatically without any manual intervention.
