Product image.
A gravel vacuum pulls detritus out of the substrate during a water change, and the main fork is a faucet-connected changer versus a bucket siphon. A faucet system drains and refills straight through a sink so you never haul buckets, while a bucket siphon is cheaper and simpler for smaller tanks. Match the hose length to the distance from tank to sink, prefer a squeeze bulb or shake-start over mouth siphoning, and remember wider tubes clear gravel faster but disturb sand more.
