Simultaneous use of Bacter Gen M or Bacter Clean M to establish and sustain growth of proper microorganisms and recycle aquarium nutrients will greatly benefit all algae and the ecosystem in general. The use of Reef Micro Fuel or Reef Bio Pellet Fuel will provide additional carbon for heavy chaeto growth. Growth of all photosynthetic organisms also requires strong lighting of proper spectrum. Consult your lighting supplier for assistance in the proper type of light, and photo periods for the algae that you are growing. Be sure to ask lots of questions to get the very best lighting system for your aquarium.
