yup, if you don't have a canister w/ tubing outside the tank you can't plumb it in.
if you do have it though, they're spot on all the time, and don't have to worry about turning em off when doing maintenance and if they run dry, they will auto shut off.
they do cost a bit more, but it goes nicely behind/under the tank so you don't see it.
