When you use dolomite lime or wood ash or whatever you want to raise PH gradually and not shock it up unless it doesn’t have plants in it and you are getting it ready for another grow.
Dolomite lime isn’t as fast as wood ash especially if you put it in water and let it steep for a few and then use that but again go conservative baby steps.
I use this for measuring soil PH
Couple different names but they all look like from same maker and I wrote up a review of how I use them and how they work
BTW jus5 by adding organic compost or worm poop that will help move PH upwards as it helps neutralize the acids that tent to collect as soil ages but again is a slow process because usually soil at bottom gets more acidic or faster than top does…my understanding anyway and what I’ve experienced
If you do use dolomite lime look on package and see what ratio of Calcium to magnesium as it may not be optimal
Shoot for a 3 calcium to one magnesium or there about and if needed add something with just calcium to get ratio like oyster powder or crab meal etc
