There shouldn't be any side effect except your ph being increase to what its meant to be. How much would depend on what else is there in your tank, e.g. coral chips, woods, etc.

The German peat makes an excellent bio-filtration substrate. There is not much pH action from peat, unless you have not much buffering in the water.
You may want fresh peat for it's beneficial effects , but old peat is good as a substrate, no problem.
