Usage of SUMP..

[sushant]

that means in time of water change we done need to start new process..

in a stablished tank if proper care is taken not to destroy the beneficial bacteria (like using dechlorinated water, partial cleaning of filter media and restrict using from using chemicals that can kill the bacteria eg. antibiotics) then u don't need to restart the cycling process )
