| I do about 30-50% a week. I have no problems with chlorine so that is an advantage. I have a timer on the hose and at least once a day (when nobody is under the shower) let it run full blast into the pond and overflow to waste. In general this is about 600-1000 liters a shot depending on how often I do it each day. I tend to turn it on when ever I walk past it The more water you change out the better.
