I'm confused. Lifeguard, $63 pH test kit.. hmmm.
For $5-10 or so, you can buy a liquid reagent pH test kit at a fish store or online. pH is probably the least important parameter that gets the most attention (for unknown reasons). I'd be interested in validating that pH though, as I've never heard of out of the tap readings of more than 8.2. Regardless, if it's stable, leave it. Just don't get any south american cichlids that only breed in soft acidic water if you want to breed.
