Choose your cleaning method

Manual gravel siphons: Explore compact, fixed-length and extendable cleaners for different tank depths. Selected models include priming bulbs, flow controls or bucket clips.
Powered gravel vacuums: Compare the Eheim Quick Vac Pro and mains-powered Fluval ProVac for collecting debris through their cleaning filters. Check operating depth, substrate suitability and any water-change accessories required.
Filter-connected cleaning: The Fluval FX gravel vacuum attachment is listed for connection to FX4, FX5 and FX6 canister filters. Check your exact filter model and required fittings before ordering.
Water change systems: Browse Bioscape long-hose water changers, Dalua siphon equipment and hose holders. Compare hose reach, tank attachments and tap-connection requirements.
Replacement parts: Find selected Fluval cleaning bags and filter pads, plus Eheim Quick Vac Pro components. Match the cleaner model and part number; replacement consumables are not complete vacuums.

Match the cleaner to your tank

Consider aquarium depth, access around plants and ornaments, substrate grain size and the amount of water you want to remove. A cleaner designed for gravel may not suit fine sand or planted-tank soil, so check the individual instructions rather than assuming every model handles every substrate. Debris collection and water removal are different functions: compare how each cleaner operates instead of treating every powered vacuum as a water changer.

Other cleaning products and delivery details

The collection also includes an Eheim Vac40 pond cleaner listed as a special-order item and URS cage cleaner for terrariums and animal enclosures. These have different applications from aquarium gravel vacuums. Selected longer gravel cleaners attract additional bulky-item delivery charges; check each listing for included accessories and purchasing conditions.
