Bacopa Australis

Bacopa Australis is rated as a medium-light plant. 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 optional for it, and its care difficulty is listed as beginner.

No, CO2 is optional for Bacopa Australis. It grows without injection, and adding CO2 mainly speeds up growth. It is a medium-light plant. For nutrients: tolerates inert substrate with occasional root tabs. Keep light, CO2 and fertilizer in balance, because raising one without the others is the most common cause of algae in planted tanks.

Cut healthy stems and replant. Some species split rhizomes. When dividing a rhizome, keep several healthy leaves on each piece and plant or attach it so the rhizome itself is not buried in the substrate. New growth comes in fastest when the tank matches its needs: medium light, with CO2 optional.

Yes. Bacopa Australis is listed at beginner difficulty. It needs medium light, CO2 is optional, and for nutrients: tolerates inert substrate with occasional root tabs. Stable light, nutrients and water changes matter more than any single product. Check these needs against your current setup before buying.
