You must then be able to measure the dose based upon the total volume and the instructions. This can be difficult for many because of poor instructions and mixed units on the container.

Pond conditioner chemicals for removing chlorine and chloramines in fresh water being added to a pond are commonly available and sold in large amounts. In my opinion these chemicals are not really necessary but at least they do perform a specific function and do little harm.

Any chlorine in pond water will normally have disappeared naturally after short time.
