Answer: Algae growth soars when warmer spring temperatues occur but aquatic plants haven't yet spread enough to cover the pond surface. If your pond is small or shallow, algae will bloom happily. You can control it with oxygenating plants and debris eating pond dwellers. The algae clearing plant formula is one bunch of oxygenating plants per 2-3 square feet of pond surface. Water snails can help eat algae and tadpoles are helpful since they eat plant debris. If your algae problem isn't solved by these natural controls, you may have to resort to a chemical algaecide, but one that's nontoxic to fish and plants.
