ph is 7.2

Is it a good idea to keep my ph between 7.2 and 7.4 to keep metal stains from forming I think I read that somewhere?

Yes, lower PH levels do help prevent metal stains. However, in most situations the PH tends to rise, and it will rise more quickly when it starts low, creating an unstable situation. With attention, you can maintain the PH that low, but it doesn't make for a good long term solution.
