Aragocrete Rock

Hello Everyone: I made some rock using the recipe from GARF. It has been soaking now for a little over 2 months. How soon can I add it to my tank?

I have live animals in my tank and I don't want to cause them harm. So, at what pH level will it be okay to add the rock to my tank?

The rock will be cured when the pH of the water you put the rock in doesn't change. If you soaked them in pH 7 fw, the water should stay at 7 with the rock in it.

The rocks have been soaking for over 2 months now with weekly and then daily water changes. I have noticed no difference really in the pH. Also, I am told that it will react differently in Saltwater than it does in Freshwater. So, if it raises the pH of my salt water, what is a dangerous level for my animals?
