Do you gravel vac sand?


Recommended Posts

Never, but then again my sand is very fine. Gravel vac is called gravel vac for a reason, it "needs" to be done due to all sorts of gunk getting trapped in the crevices between the gravel bits giving potential growth areas for harmful bacteria. Might be an aquarium myth, but loss of barbels on cories has at least partly been attributed to such bacteria.

Most of the stuff that remains on the bottom gets eaten by my trumpet snails, who are in there to keep the sand loose and.. aerobic I suppose, by digging around and hiding in it. Of course my tank wouldn't qualify as a show tank as I don't mind some "trash" on the bottom.

Most of the trash gets picked up by the pre-filter sponge of my canister filter and internal filter anyway.
