hey evryone i was looking to get a pair of hognose snakes till i went camping and saw a water snake(caught and let it go back the next day)

and decided i might wana get a pair of them

so i was making some cage plans and was gunna put a half water pool and the rest dry land with a under ground hide spot for themto go in and so i can still look at them.

what do you guys think i should do for the water like what system should i use to keep it warm and clean.
it might be like maybe 10 gallons of water.

thanks for your help
