Subwassertang (Round Pellia) (Lomariopsis lineata) aquarium plant care.
Subwassertang (Round Pellia) is rated as a low-light plant, with a target of about PAR 15-30 at the leaves. Low light means a basic aquarium LED is usually enough, and adding much more light without matching fertilizer tends to feed algae on the leaves before it speeds up the plant. CO2 is not needed for it, and its care difficulty is listed as beginner.
No. Subwassertang (Round Pellia) does not need injected CO2, so it suits low-tech tanks without a CO2 system. It is a low-light plant, with a target of about PAR 15-30 at the leaves. 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. Trim stems just above a leaf node, push the cut tops into the substrate, and the trimmed base will usually branch and regrow. New growth comes in fastest when the tank matches its needs: low light, with CO2 not needed.
Yes. Subwassertang (Round Pellia) is listed at beginner difficulty. It needs low light, with a target of about PAR 15-30 at the leaves, CO2 is not needed, 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.
