    I usually guess by watching the side of the tank. If I want to remove about 25%, then I judge what looks like 1/4 of the tank height. A little more should not hurt and I usually judge on the side of more than less. If you are asking so that you can guess how much water conditioner to add, again, I will add more than I might need rather than less.

    I hope this helps.
