Egeria Najas: oxygenating plant with ultra-fast growth
L'Egeria najas is a little-known relative of elodea (Egeria densa), but even more robust and vigorous. It grows at an impressive rate, absorbing nitrates and phosphates and thus greatly limiting algae growth by starving them. It also has a specific effect against cyanobacteria thanks to its natural antibiotic molecules with antibacterial properties.
Versatile and resilient, it adapts to many conditions: soft or hard water, variable pH, low or intense light, herbivorous fish, snails... It oxygenates the water abundantly (you can even see it "bubbling"!), thereby contributing to the overall health of the ecosystem.
An extremely effective natural filtering and algae-fighting plant, perfect for ponds, aquariums and tub aquariums.
Why choose Egeria najas?
- 🚀 Rapid growth: up to several centimeters per day!
- 🛡️ Excellent natural filtration and effective control of algae and cyanobacteria
- ⚖️ Tolerates a wide range of water parameters
- 🌸 Suitable for ponds, tub aquariums and low-tech aquariums where it will flower readily
- 🐠 Very resilient against herbivorous fish and snails
- ⚓ Can be left freely submerged mid-water or planted in the substrate
Planting and care tips
- Can be planted in plain sand or left to float freely mid-water
- Easily propagated by cuttings: cut a stem and replant it
- Loves light but also tolerates less well-lit areas
- Highly oxygenates the water, often visible through its photosynthesis bubbles
- Regularly remove a few stems to prevent it from becoming too invasive
FAQ - Egeria najas in aquariums & ponds
How big does it get?
Up to 60 cm, depending on the space and conditions. Some stems may be longer but then break easily to form two.
Can it be planted in sandy soil?
Yes, it adapts perfectly to plain sand since the soil is only used to anchor it. It only feeds in the water.
Does it flower?
Yes, its flowers are very similar to those of elodea: right at the surface, a few ivory-white petals crumpled like tissue paper!
Can it live with goldfish?
Yes, even the hungriest herbivorous fish can't get through its tough leaves! Goldfish prefer duckweed.
Is it suitable for outdoor winter conditions?
Yes, it withstands the cold but stops growing during the cold season. It starts growing again in spring, a little later than the elodea.
