omg lol. well my husband doesn't even get why i change the water every week! let alone test for it. he thinks that i have ocd or something cos i test often etc. hmmm i wonder what he'd say if i asked him to test the water?!
He's sweet for wanting to help. It was just funny, and we get a lot of "Well, this question is dumb..." so I thought I'd point out that no matter how dumb, it's better to ask. (Although I have to admit that I am not one of those "there's no such thing as a stupid question" people. There are stupid questions, but they should be asked anyway.)
