Ignore it. You can do more damage chasing pH than just not knowing what it is. Keep the alk stable and good and ignore the PH.
The only exception to this is if you are using an Muratic for alk control or some Kalk for supplement.
Your pH is fine. Don't beat yourself up trying to hit a target value. Stay within the ideal ranges and shoot for stability. Just my .02
+1 In my experience, chasing ph is fruitless.Ditto with the above. Focus on the alk, not the pH.
Quick question for those saying to worry about the alk not the pH. I was under the impression that a pH of 8.3 is desirable for coral growth. In fact, I am positive that this has been said a number of times in various BRS videos like 52 Weeks, and 52 FAQ, etc.
Are they wrong?
