which ro water to buy ?

[lobsterboy]

thanks for the info everyone, i do live in an apartment so i didnt want to start to mess with the plumbing and such.

so the main reason for the ro water, is i now have an auto top off, instead of me coming home and manually replacing water, i thought that the tap water that i use straight from the tap into the tank, might sour or go stale if i was sitting for awhile.

any thoughts on tap water going stale?
