High Ph Help

[littlecam]

Hey everyone...I just took some readings on my 90gal and it looks like my ph is really high. All other reading look pretty good. We have really hard water out here and I heard that might cause ph to raise. Can someone tell me how to lower my ph which I never had to do in the 8 years I have had my tank. Also is this going to affect my fish at all? I have a trigger and I just added a snow flake eel and a Dragon wrasse before I new my reading were off. I hope this doesnt hurt any fish. Please give me some feed back?
Thank you,
