Aquatop EZ Vac-N-Fill Aquarium Water Changer Kit
The Aquatop EZ Vac-N-Fill turns water changes into a one-step job. It connects straight to your faucet, so you can vacuum debris out of the gravel and then refill the tank from the sink, with no buckets, no spills, and no hauling water across the house. Three brass adapters fit most faucets, and a heavy-duty PVC hose reaches from sink to tank. Finish every refill with a dose of Fritz Complete to neutralize chlorine and chloramine, and browse the rest of our aquarium cleaning tools.
How It Works
Thread an adapter onto your faucet, run the hose to the aquarium, and turn on the tap. The running water creates suction that siphons dirty water and gravel debris out of the tank and straight down the drain. When the tank is at the level you want, switch to refill mode and fresh water flows back in through the same hose. Match the temperature at the tap and add a water conditioner as it fills.
Features
- Vacuum and refill in one. Clean the substrate, then refill through the same hose without swapping gear.
- Universal faucet fit. Three brass adapters included: 15/16 inch internal, M21 external, and 3/4 inch external, to fit most standard faucets.
- Built to last. Corrosion-resistant brass fittings and a heavy-duty PVC hose for years of water changes.
- Fresh or salt water. Works on freshwater, planted, and marine aquariums alike.
- Bucket-free. Dirty water goes down the drain, so there is no lifting and no puddles.

Frequently Asked Questions
Do I still need a bucket? No. Dirty water siphons straight down the drain and fresh water comes back through the same hose.
Will it fit my faucet? The three brass adapters cover most standard kitchen and bathroom faucets. Pull-out sprayer faucets sometimes need a separate adapter.
Which length should I get? Choose 25 ft if the tank is in the same room as a sink. Go 50 ft for tanks across the house, on another floor, or when you run several tanks.
Do I need to treat the water? Yes. Add a dechlorinator such as Fritz Complete as the tank refills to neutralize chlorine and chloramine.
