Retic questions?

[Ballchris]

Ok i have a good sized tub that no one in the house uses, I was gonna clean it up really nice and disinfect for lord voldemort, I was wondering how deep, the temp of the water, and how long should i allow my snake to swim I have been doing some reading on the matter but can find nothing on the questions just that they like to swim in the wild. and iv seen pics of people letting there retics and burms swim I think the big guy would enjoy a nice dip.

so How deep should the water be
how warm
and how long should I allow him to swim?

thank you very much in advance.
