Will my pond or water feature have Algae?

Yes… Water, air and sun are the ingredients for algae. There are many species and sub species of algae, but for the sake of argument lets classify algae into two groups for now. 1) Platonic algae is the pea soup colored water often associated with ponds and stagnant water. String algae is the flowing strings or matts of algae, but your water is clear.
