...of refill water on my carpeting, wood tank stand, dog, and cat, I've concluded I'm too klutzy to use a bucket. Started using a watering can but that takes a zillion trips to the faucet. Stumbled across a video mentioning the Python water changing system, and it sounds like there are also other similar options out there. So I'm wondering, are these systems worth buying? Which brand do y'all like the best?
