Welcome to the forums Firstman. I'm sorry to need to tell you this story. I'm afraid that either your test kit or your LFS has been selling you something you don't need.
Chemical additives are not organic like we deal with on a cycle. They will act almost instantly. That is one of the big dangers in using them. The fish are organic and can't really keep up so they get stressed by the rapid and frequent changes such products cause. The real question is why you would try to change or buffer your pH. The problem becomes that the underlying chemical composition of your tank water is very difficult to alter. To do so requires quite strong acids that will quickly change things. The next thing that happens is that whatever caused the original pH that you are trying to overcome is still present so it will slowly go back to where it started. Then you add the acid or base again and get the rapid response, another stress cycle on the fish, then it drifts back to where it started. repeat until you are broke or your fish are sick or both.
Almost all of the common fish that we keep can live out their lives in comfort between about 6.5 pH and nearly 8 pH. With that in mind, you are usually better off leaving the pH where you find it. It will not cause the cyclic stress of chemical adjustments and your tank will flourish.
