How big is your tank? For my smaller tanks,I just use gal. milk jugs.I don't really have any problem with stirring things up. I've actually done water changes on my 75 gal. that way too.

I finally had to break down & use the water python that my daughter got me for Xmas.

I let it sit for months because for some strange reason,I like to see what comes out of the tank!If your tank's bigger,the Python works well for filling & not stirring up a mess.
