How to lower Ph?

There are actually commerical products that will lower Ph (they even sell pHup and pHdown products) I'd be a little wary of dumping them into the tank unless you had a non-living sump though: you want to go pretty slow when changing pH. The real question is why is it high to begin with: most salt mixes are designed to get it right simply in the mix. Be careful about switching mixes though... ask people here before you try.

What kit are you using to test? What are your other water parameters, especially alkalinity and magnesium? What salt mix are you using, and have you tested it before adding it to your tank? What is your tank setup like (size, lighting, filtration, etc)?

You need to test for Alkalinity, Calcium and Magnesium. These are likely out of whack in you tank, and air tubes won't solve this problem. These are not the greatest test kits, either. I would invest in some higher quality test kits.

Increasing oxygen in a tank can elevate ph, not lower it.

saltwater tanks shouldn't have bubbles: better to have powerheads agitate the surface than to have them spew bubbles. You can bubble your water change and topoff water though.
Your salt mix should really be setting the ph right from the start. Test some just mixed saltwater and see if it's correct. If it is, then something else in your tank is messing with the ph, and you need to figure out what.

I would try a different test kit, chances are your PH is really not that high, usually if it goes over 8.5 there is a problem with the test, Randy Holmes Farley has some good articles on ph, and how to raise and lower, lots of good info on ph, would be a good thing to research to figure out what is best for you.

Comparing against a different PH test kit is a good suggestion.
Take the venturi tubes off the powerheads, they'll just cause salt creep.
Mix up a batch of saltwater and let it sit for 24 hours and then test the PH. It's possible you have a bad batch of salt, it happens.
Test the water in the morning and in the evening, not just once.
DON'T ADD ANY CHEMICALS to bring ph down. you need to find the cause before you can have a good solution.
