We have found that the Blue light tends to push the early corlalline algae growth. It is fun to plant the arch kits with fast growing corals and then watch as they become covered with valuable colonies. This arch has started to fill in very well. Some of the corals are growing faster each time we cut a new clone. Corals adapt to closed systems better after they have been in our care for several years.
Coralline algae seems to do the same thing.
We are certain that many strains that we put in our Grunge tm are able to grow in aquariums better now that they have been in Idaho for several generations. I start out my tanks with blue moons and Tritons and work hard focusing on healthy coralline algae growth. This is the tank that we put the crushed coralline algae rock in The Complete Bullet Proof - Zero Impact Reef Aquarium last month. Sally Jo already has over 50 types of soft corals growing in this reef. These three reefs are grown to be brood stock aquariums.
