Agreed
Try performing 10 instead of 15% weekly changes, or do 15-20% every 2 weeks
This will let your Alk level drop some through usage as you are most likely adding more Alk to your tank with WCs than your tank is using right now
Of course, this is barring you needing to change water due to Nitrate or Phosphate issues
Your corals and skimmer will let you know when you need to change water, so don't fret so much about doing weekly changes to start with
I notice I need to do a WC when my skimmer starts to act up/create less foam/overflow, or my LPS corals start acting as yours have with lots of clamping/closing
I'm not saying this is when I change my water, just that this is what I've noticed as I've gotten used to my tank
I also know when I need to do a carbon change for the same reasons as, when the organics from corals fighting builds up in my mixed reef, I start seeing signs such as less skimmate and clamped/closing softies/LPS, and new algae growth
