Ph and kh are a little low...

[recliner]

Just tested for everything I can...
PH- 8.0
Kh - 125
Nitrite - 0
Nitrate - 0
Calcium - 460
Phosphate - between .25 and 0
Ammonia - 0
Salinity - 24
Temp - 77
My question is about the ph and kh. I have some instant ocean sea buffer that says it increases ph and alkalinity. The instructions say to add 1 teaspoon per 10 gal daily to reach desired levels. Since I'm not far off my levels I was thinking of adding 3 teaspoons and retesting in 2 days and repeating that until I get them up to the right levels. Should this work or are there better options?
I'm guessing that my 150 gal tank plus refuge have about 125 gal in them together accounting for all my rock and sand.

Your pH level is totally fine, 7.7 would be low, 7.8-8.3 is fine. Also, your Alk is at the low end of acceptable but it's fine, reccomended level 125-200. I wouldn't dose anything, maybe try a 10-20% water change and see if the level changes at all.
