I second that. pH strip is plenty good if you just want to know the pH of your tank. No kit is necessary.I used the pH strip in my tank once and it worked great. But for my pH strip, pH7 is a deep green and shortly after turning green, the color started to come off and disperse in the water. So I would recommend maybe getting a small cup of your tank water and testing the pH there...
Stuff that changes the pH of the water includes turtle waste (e.g. ammonia is basic i.e. greater than pH7), decaying food, etc. I read somewhere that a slightly acidic pH is good (pH 6.5) because it curbs bacterial growth.
FYI:
- pH values are on a log scale from 0 to 14, meaning that pH0 is 10 times more acidic than pH1, which is in turn 10 times more acidic than pH2, so on and so forth.
- pH0 is most acidic (even more acidic than concentrated sulfuric acid)
- pH14 is most basic (concentrated sodium hydroxide is about pH12)
- pure water should be at pH7, but trace chemicals in it would throw the pH off a tiny bit
