What kind of fertilizer to use? I have had my pond

3 years and have never fertilized because I was afraid it might endanger all the wildlife that play/drink in my pond and that it would provide food for the algae to grow too. I have several koi, lots of plants, frogs, and snails. All my plants seem to be doing extremely well. I have them planted with rocks, not in pots, and they are quite prolific and I have to thin plants out yearly. Do I even need to worry about fertilizing?
