hey Joe, a little planting instructions i forgot to pass on. the long strand of prolifera will root on sand or rock with its hold fasts ,as will the short strand of razor caulerpa. the little sprout of halamedia is calcium based in structure and can be glued down with super glue gel. the itsy bitsy stem of red grape,(sorry only have a few small sprouts at at the time) and the red gracillaria can be tied down to a small piece of rock and hopefully attach in time.
If there is enough nutrient, light and flow in the tank, they should do pretty good and grow. keep them pruned.
hope that's what you were looking for.
