Possibly cyano

It is an epiphyte similar to cyano and is caused or encouraged by a number of reasons including:

Available nutrients - Especially phosphates and iron in this case.
Low flow/Dead Zone - this stuff grows in low flow areas.
Warmer Water - It tends to grow faster in warmer water than in cooler water.
Low Alkalinity- While not a cause, higher alkalinity tends to discourage its' growth.
Possible "contaminated" water source like tap water, that has nutrients fueling the outbreak (old RO cartridges.)

Lower white light intensity, adding a pouch of chemipure elite will help. Also, increase water changes to 30% with a high quality water source, such as distilled or RO/DI water. Be aggressive about removing any rotting organics in your tank that may be contributing to its growth.
