How do I lower it? I realize I'm limited on what type of fish I can have in a small tank. I guess I'm even more limited with the pH.
pH can be hard to lower but many fish prefer high pH. I would research what each type of fish you would like to get prefers in their water.
As for why you might have high pH, it might be in the decorations in your tank. substrate such as crushed coral raises pH as well as rocks, or shells or anything not specifically meant for aquariums can leach out chemicals.
To lower pH, I wouldn't use chemicals, as most of the time they are only temporary.
Things such as driftwood, & Almond leaves do this naturally. I would also research peat moss.
