Care
Shining pondweed is a large pondweed of lowland lakes and slow rivers with hard, limy water, usually 0.5–2 m deep. Stout rhizomes send up long, branching stems, typically up to 2.5 m (rarely 6 m), with big, shiny, translucent pale green leaves 7.5–20 cm long and finely netted veins. It has no floating leaves. Wikipedia calls it attractive and easy to grow, though rarely cultivated; it is mostly a plant for garden ponds and barrels, rooted in sand or aquatic compost and weighted down at first. Young plants may need protecting from birds and fish. It is a temperate plant and does poorly in heated tanks; in a large coldwater aquarium it makes a bold background plant. The pH and hardness reflect its calcareous habitat; temperatures are our estimate. Sources: Wikipedia (en.wikipedia.org/wiki/Potamogetonlucens); Wikipedia, List of freshwater aquarium plant species.

Breeding
Divide the rhizome; stem cuttings root poorly.
Compatibility and tank mates
Goldfish and waterfowl graze it. Suits large coldwater tanks and ponds.

Buyers are told to pay by PayPal Goods & Services, never PayPal Friends and Family, gift cards or crypto.
