Yeah, I had some lying around from a freshwater tank that I had years ago, they were pretty old and I checked them in RODI water and the test was off.

If you wanted a quick PH test, try using the ones that they use in chemistry classes. I know there cheap and accurate an I've used them with pretty decent results. The only problem is there not too specific but I'm sure there are ones out there that get pretty accurate reads.
