I see.
How fast does the limestone take to raise the pH?
Yup, ocean rock is limestone and is great for raising the PH, Google ocean rock or Texas holey rock as its the same stuff but just called something different in the US compared to the UK.

I'm not sure on speeds of it raising PH as it depends on your tanks PH already, water volume and the rock size :p

Don't get it confused with 'live rock' stay away from that as it will pollute your tank when all the ocean life dies off from it in the brackish conditions.

Ah, okay! I'll try to find it in my LFS before searching/buying it online. Hope it's not too expensive! :dead:

The stuff you want is also known as "dry rock" in the reef community.
