Azolla Fairy Moss (Azolla filiculoides) aquarium plant care.
Azolla Fairy Moss is rated as a medium-light plant, with a target of about PAR 30-60 at the leaves. Medium light is roughly what a mid-range planted-tank LED delivers over a standard-depth tank; going brighter without more CO2 and fertilizer usually shows up as algae rather than faster growth. CO2 is not needed for it, and its care difficulty is listed as beginner.
No. Azolla Fairy Moss does not need injected CO2, so it suits low-tech tanks without a CO2 system. It is a medium-light plant, with a target of about PAR 30-60 at the leaves. Keep light, CO2 and fertilizer in balance, because raising one without the others is the most common cause of algae in planted tanks.
Splits via runners. Let each new plantlet grow its own roots and a few leaves before cutting the runner, then replant it at the same depth as the parent. New growth comes in fastest when the tank matches its needs: medium light, with CO2 not needed.
Yes. Azolla Fairy Moss is listed at beginner difficulty. It needs medium light, with a target of about PAR 30-60 at the leaves, CO2 is not needed. Stable light, nutrients and water changes matter more than any single product. Check these needs against your current setup before buying.
