Yes, you do have to water it. About once every few weeks.
Pools should be chemically tested at least once a week. However, during periods of heavy use or hot weather, it's advisable to test the pool water 2-3 times per week to ensure proper chemical balance.
No.
I once heard that real patent leather will not leave fingerprints when you touch it (at least if it is a good quality). I tested this at Nordstrom's once per the counter girls advice and she was right.

You need to test for ammonia once a week (and all aspects of water quality) for established aquariums (see related question). In newly setup aquariums (up until the tank is cycled), test ammonia (and all aspects of water quality) every other day. since i set up my tank(18 months ago,i have never tested for ammonia.once your tank has cycled there is no need unless you have a major catastrophe like a large fish or anemone dying. You should test ammonia for the first 8 weeks of your cycle. After that, there will be enough bacteria in your tank to convert ammonia into nitrite and there will be no need to test unless there are signs of problems.
