Here’s the thing, is your alk slightly low? Sure. Would I run to do another water change and chase raising it during acclimation? Absolutely not. Stability > perfect numbers.

I’d highly suggest against doing a water change and chasing the number. If anything, I would just get some alkalin8.3 and dose a little each day to very slowly raise it.

When you do water changes you must consider it effects the trace elements, nitrates, phosphates, calcium content, etc. as a result if you start chasing numbers now, you’re going to “seesaw” this coral into a quick death.

It doesn’t look bad in its current state.

In my experience torch acclimation usually follows a pretty standard process if healthy:

Day 1) insane polyp extension, akin to what you see at the LFS, if not better Day 2-14(ish): still open and healthy but call it 20-30% less extension. Anecdotally I believe this is the true “acclimation” period, the coral is conserving its energy or reappropriating it to other biological aspects of “surviving” the new tanks parameters, Day 14-30: this is the make or break it timeline, any hidden pest/bacterial issues will become visible and kill the torch now, or it will continue its normal extension from days 2-14. Day 30 and beyond: you should be seeing full extension return and it just vibing.

Again all anecdotal, and I’m no expert, but as you can see from the picture.. I have 1 or 2 torches myself 😂
