It is time to put up this thread. Other Threads have been talking about old School systems and implying, we didn't know what we were doing.
My system for water changing:
It relies on the tank to be Heavily planted around 50%, acid water, natural neutral base. Good filtration.
Then it is possible to safely do 25% water changes using no Dechlorinator, this works for town supply water that has Chlorine in it.
When refilling the tank you bring the garden hose in and fill the tank with the spray nozzle. The tank water will drop 3-4 degrees which is not a problem for the fish.
As the water hits the tank almost all the Chlorine is dissipated into the atmosphere the little bit remaining is absorbed by the system.
I have been using this system for water changing for over 40 years.
