How To Control Algae

• The intensity and quality of light they are exposed to.
• The amount of nutrients (DOC's - Dissolved Organic Compounds) they have to feed on.
• The amount of nitrates and phosphates, and for diatoms, the silicates they have to feed on.
• Using an improper make-up or top-off water source. (Tap water usually contains nitrates, phosphates and other unwanted elements).
• Using a poor quality sea salt mix. (One that contains nitrates, phosphates or other unwanted elements).
• Poor or inadequate aquarium maintenance care. (This allows excess amounts of nitrates, phosphates and other unwanted elements to accumulate).
• Low water flow or circulation in the aquarium.
• No natural algae eating predators.
