A good rule of thumb is don't put anything in the tank that you don't have a test kit for. My guess is your pH is so high because your reactor isn't set up quite right. You need to test for alkalinity also, as I imagine that number is way off also. It should be in the 8-12 dKH
I've found that for basic tests such as pH, ammonia, nitrites/nitrates that API tests are a great value. Easy to do, pretty accurate, and pretty cheap. For the other tests such as Calcium and Alkalinity, Salifert is definitely the best. You'll want test kits for all these things, and probably a Phosphate test if you're keeping a bunch of corals.
As others have mentioned, don't drop that pH too fast. I'm surprised you're not having other issues with a pH that high.
