Recipe for Coralline Algae
Light 10 hours :
1 Actinic Bulb
2 Tri Phosophor Bulbs
Calcium:
400 mg/l Calcium and it will deplete so check it regularly.
Salinity 1.024
balance Ph, alkalinity, temp, etc.
Most important a seed stock to activate the tank. Live rock, grunge, wonder mud, whatever.
Even more important patience.
Coralline algae travels in the water column until it finds an acceptable place to put down roots and grow. It will grow on just about any surface with a direct path to the light in the tank. It grows and spores off and spreads. But you need a spore source to activate the system. You will not get Orange coralline if nothing you put in the tank has Orange coralline algae on it. The more varied the source the better. I inherited the rock I had and it was mostly dead. Since I have gotten started the algae has spread out and is even on my lace rock now.
