So what do people use as a "gravel vac" to clean their substrate? I currently have sand substrate. I do bucket water changes and can't use my python water changer due to my sink connection being messed up. There are huge collections of waste (guppies) and I have no idea how to get it out effectively when I do water changes.

I have seen online some kind of special gravel vac tools. I may try this option. Anyone have any idea?
