At best I think this would be similar to adding sulfuric acid to your
water. It will lower the alkalinity and (all else being equal) lower the
pH.  You might find the aluminum sulfate easier to store and handle than
sulfuric acid.

On the down side, free aluminum is toxic to many plants.  It's probably
toxic to fish as well in sufficient doses.

I wouldn't use aluminum sulfate, and I couldn't advise you to, either.
