Whenever anyone complains that they cannot win the battle against algae, phosphates immediately come to mind. Phosphates serve as a nutrient for algae, and elevated levels will certainly add to your algae woes. Although it's rarely discussed, a leading cause of increased phosphates is dry fish food - particularly overfeeding with lower quality foods that are high in phosphates. Another source of phosphates is low grade marine salts, be sure to use only Fritz Brand Quality Salts.

Phosphates are also detrimental to corals in invertebrates when large amounts are present.
