After years of struggling with water changes, this is a lifesaver! No more buckets of water, spillages and mess every time I need to swap water out. The Python No Spill kit is amazing. This kit is as much for the hobbyist as it is for anyone living with them.
How it works is, you attach it with the included brass adapter to your faucet (or an optional universal adaptor). Then you run the water. The force of the water coming out of your faucet draws the water out of the aquarium. The aquarium water is flushed away with the water from the faucet, down the drain. To fill the aquarium you can add a threaded fitting to a utility pump. Place the pump in a bucket of premixed, preheated water, and fill the aquarium back up. Brilliant.
The good news is that each component of the kit is sold separately, so if you need to adapt the kit to suit your water changing, it’s entirely doable.
