Oyster Shell Application Rates For Ph

[Growin Grass]

I'm sure this is somewhere but I have to go to work and don't have time to waste googling shit
can anyone give me a ballpark number to raise say 1.0ph per gallon of soil?
Yes I know there's other stuff to use bla bla bla but this is what I have and will be using
Thanks folks

Ok so I never found anything about that but after some reading it looks like Dolomite is going to be the way to go. Seems like how much Shells with adjust your PH can vary depending on your soil, the oysters, how long they sat outside getting rained on before being crushed, how crushed up they are, and it takes time for the ph shift. Don't have a lot of money to be throwing around on the garden right on and was hoping to use what I have... but to the store I go
Also gonna post some stuff I read about Ca in another thread
