I start by syphoning the tank water through a hose out the door and into the garden.
As that hose is running i give the tanks a quick gravel vac into buckets just to remove any visible poo or waste.
Then i fill up a 100L rain tank with tap water, add some prime then pump that into the tank, and repeat if necessary
