Indeed that's the "easy" and most common method, Bill. But when I first tried it years back I found it just clumsy enough to be annoying.
Even with a funnel, it was hard to get bleach safely into the hose without getting the stuff on my clothes or skin, and then I had to figure a way to keep it in there while I tried hooking to the spigot. Putting a separate inline shutoff on the end was an option relative to that issue.
But then I found the bleach didn't chemically agree with the hose, leaving a vague taste in our tank that was hard to get rid of. I swore not to do it like that again, and invented an alternative method as related in this older thread:
