If you use a municipal water source, you must be careful with the chlorine & other chemicals the cities use for purification. They can be deadly to fish. I have an auto fill on my pond which replenishes water little by little as the water evaporates. The Koi can handle the small amounts of chlorine in my city water this way.

Linda glad to hear your watercress is still doing well. Mine bit the dust a long time ago. Suppose I should pick up another bunch when I am at the market.
