Kleiner Bar Sword (Echinodorus var.) aquarium plant care.
Kleiner Bar Sword 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 optional for it, and its care difficulty is listed as intermediate.
No, CO2 is optional for Kleiner Bar Sword. It grows without injection, and adding CO2 mainly speeds up growth. It is a medium-light plant, with a target of about PAR 30-60 at the leaves. For nutrients: plant in nutrient-rich aquasoil with 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.
Divide rhizome or runners; cut healthy stems and replant. 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.
