200g (probably 180g water) 8 months.
SG: 1.029
alk cal mg: 10.2 390 1460
Nitrate phosphate: ??? Do not test, if SPS is good I'm good.
water change 25g every 2 weeks, sometimes 1 week if issue.

I would look at the measuring kit or device you are using. You made many moves that should have changed it even slightly.
I recommend a water sample to a trusted LFS and see what they come up with for a reading.
You may add Kalwasser diluted to sump, pickling lime and even ALK liquid to help elevate.
Baking soda will also elevate BUT. . .. Test water First in the event it is higher than you are seeing

Your #'s don't look that bad, SpGrav could be lower. I like 1.026. Cal is low but not extreme. What are you measuring PH with? Maybe probe needs calibration. I would take a sample and have another reefer or LFS test PH.

I wouldn't expect that low of a ph with stable higher level ALK. Makes me think maybe probe needs cal or went bad. I would verify first. Also would consider a CO2 reactor - no too expensive - i have one from BRS. Raised my PH from 7.8-7.9 to 8.1-8.3.

I doubt that number is accurate. Is everything in the tank doing fine? Corals, fish, and other inverts? You will cause problems chasing pH. My recommendation is to stop testing pH and never look back.
Use some kalkwasser in your ato, boom. nothing catastrophic will happen to your tank with low (consistent) PH, but your corals will grow way better with more normal Ph. This has been proven to a decent degree now.
