I am looking to upgrade from using a 5 gallon bucket and siphon to a python water changer. My tank is only a 10 gallon tank with a betta and two nerite snails, but water changes have become a pain as I somehow find a way to get water everywhere when going from the bathroom back to my room where my tank is. Which python would be appropirate for a 10 gallon tank? Is it able to hook up to a bath tub spigot, or does it have to connect to a normal sink? Thank you!
