Pros and cons
- Creates a 'meadow' floor effect
- Reproduces without intervention — runners across the substrate
- Great for shrimp tanks — juveniles hide between the blades
- Needs a nutrient substrate (root feeder)
- Often melts back in the first weeks after planting
- Knits into the substrate — replanting is hard
Description
Creates a 'lawn' of fine 10–15 cm blades. Spreads via underground runners — gradually covers the whole assigned area.
Care
Nutrient substrate, medium light. Without CO₂ it grows slower but still forms a lawn.
FAQ
- Почему ситняг таёт после посадки?
- Адаптация. Старые надводные листья отмирают, под водой отрастают новые. Через 3–4 недели начнётся рост.
