Having coralline algae in a marine aquarium is not only an indicator of ecosystem maturity but also a source of pride for many beginning marine aquarium enthusiasts. The presence of coralline algae signals that the aquarium is ready to be inhabited by more demanding corals.
In this article, I will present a simple method to speed up the colonization process of coralline algae in the aquarium.
One effective way to accelerate the growth of coralline algae is to obtain samples from a well-functioning tank belonging to a trusted aquarist. These algae can be easily removed, for example, from the aquarium walls or the filtration chamber (sump).
It is important to dip the received piece of coralline algae before introducing it to our aquarium. This will prevent the accidental transfer of unwanted organisms to our main tank.

Once the coralline algae has been dipped, place it in a small container filled with water from your marine aquarium. Next, using a suitable tool, grind the coralline algae into the smallest possible pieces to achieve a consistency resembling ground ingredients.
In the next step, pour the crushed algae directly into the aquarium. Before doing this, it is a good idea to stop water circulation and movement to allow for an even distribution of the algae on the rock surface.
Summary
By using this method, the algae should attach to the rock and colonize our marine aquarium more quickly. Of course, for coralline algae to grow, it is necessary to maintain the proper water parameters, such as levels of calcium, magnesium, strontium, and iodine. Therefore, it is important to ensure the correct concentration of these elements.

Reefkeeping has been my passion for over 10 years now. I love learning. The hobby has taught me many valuable lessons, patience being the best example.
Combining work and passion is my path. I run Crazy Coral, a marine aquarium shop, for a number of years. Building this business from the scratch I learnt from my own mistakes at a heavy cost.
Later I managed a project aimed at development of methods for quick growth of Corals in non-natural conditions. The project was carried out by Get Sales, Poland.
Presently, I am responsible for distribution strategy at Reef Factory, of which I am a
co-founder. The company produces smart devices for marine aquaristics.
The last projects I have been involved in are Social Reef and ReefPedia.
