Yes you can use a Ph buffer , the reading you have given is not too worrying, are you testing for DKH and calcium also?

By the way Seachem do a good PH 8.3 buffer

In my experience a good way to help maintain stable ph is regular water changes. I (usually) do 5 gallon every 2 weeks on a system a little over 30 gallon.
