IMHO, I think the first thing to consider is how is all your livestock doing?
It doesn't look like anything is too far out of whack, I'm not sure about chasing a 'perfect' pH. Mine is running in the high 7's but was in the low 8's before the fires.. everything is still doing great and growing so I'm not going to make any major changes or try to 'fix' it. My alk is dropping slightly but I've added a bit of livestock recently so it was to be expected and making slow minor adjustments to my 2 part dosing schedule.
Water chemistry will change, it does in nature.. I personally think keeping reefs is about managing large swings in chemistry and not overcorrecting, creating even more problems that will need to be corrected again. Slow and steady wins the race
