Aquarium gravel & substrates are the final resting ground for the fish waste and excess food floating around your tank - even with a filter, you should clean your gravel regularly. Gravel vacuums & siphons remove particulate waste from your gravel so that you don't have to actually wash it often, preserving the beneficial bacteria that grows on it. We recommend using gravel vacuums or siphons as part of your weekly partial water changing routine. Scroll down for parts.
