Does this solution harm St Aug grass? For serious cases of algae, make a mixture of 5 ounces of copper sulfate and 3 gallons of water per 1000 square feet of turf.

This formulation will not harm St Augustine turf.
Keep in mind that this treatment will help initially but the moss or algae will return unless the conditions are corrected.
