Python Products Python No Spill Clean and Fill (25 ft) vs hygger Hand Operated 3-in-1 Water Changer
Which should you buy? Our verdict on both, pulled from our full The Best Aquarium Gravel Vacuums: 4 Compared (and One to Skip) comparison.
The Python removes the bucket from water changes entirely, which is the single thing most likely to make you keep up with maintenance on a large tank. For smaller tanks the hygger hand pump siphon does the same cleaning job for a fraction of the price and fits in a drawer.

Python Products Python No Spill Clean and Fill (25 ft)
Buy itThreads onto your faucet, drains to the sink, and refills the tank, so the bucket disappears entirely.
- Drains and refills without ever lifting a bucket
- Suction scales with how far you open the tap, so it is genuinely adjustable
- Wide gravel tube is designed to lift heavy mulm while gravel drops back
- UV-stabilized tubing made from FDA-approved materials, per the maker
- Needs a faucet with removable aerator threads, which rules out some sprayers and designer taps
- The venturi wastes tap water while it drains
- 25 feet of hose is bulky to coil and store

hygger Hand Operated 3-in-1 Water Changer
Buy itA hand pump starts the siphon, and the extension tubes let one tool fit several tank depths.
- Spliced extension tubes (16 or 31.4 inches before the head, per the maker) so one tool covers several tank depths
- Hand pump starts the siphon without mouth suction, and needs no electricity
- Includes a flow clamp, duckbill suction inlet, pipe clamp and a 79 inch outlet hose
- Compact to store and inexpensive
- You are still carrying buckets, which becomes the bottleneck on larger tanks
- The outlet must sit well below the tank (the maker says at least 19 inches) for the gravity siphon to work
