Answer
Cynthia,

With my water tester, yellow means low Ph. If on your tester it shows it high, meaning higher than what you tank needs, then its Ph down. I do not use any of those. If my Ph is off, that also means my ammonia will be off. Usually all I do is a water change. If it is very high I will do a 50 to 75% water change and then 25% water changes everyday until the ammonia and Ph are at the right level. Try doing that instead of adding a chemical to your tank. Make sure you change the filter at least once a month to keep everything under control.
