Egeria Najas: ultra-fast growing oxygenating plant
The Egeria najas is a little-known cousin of elodea (Egeria densa), but even more robust and vigorous. It grows at an impressive speed, capturing nitrates and phosphates, thus strongly limiting the spread of algae by starving them. It also has a specific action against cyanobacteria thanks to its natural antibiotic molecules with antibacterial effect.
Versatile and hardy, it adapts to many conditions: soft or hard water, variable pH, low or strong light, herbivorous fish, snails... It oxygenates the water abundantly (you can even see it "bubbling"!), thus contributing to the overall health of the ecosystem.
An extremely effective natural purifier and anti-algae plant, perfect for ponds, aquariums, and trash tanks.

FAQ - Egeria najas in aquarium & pond
What is its adult size?
Up to 60 cm, depending on space and conditions. Some stems can be longer but then break easily to form two.
Can it be planted in sandy soil?
Yes, it adapts perfectly to simple sand since the soil only serves to anchor it. It only feeds in the water.
Does it bloom?
Yes, its flowers are very similar to those of elodea: just at the surface, a few ivory-white petals crumpled like tissue paper!
Can it coexist with goldfish?
Yes, even the hungriest herbivorous fish cannot overcome its tough leaves! Goldfish prefer duckweed.
Is it suitable for outdoor winter?
Yes, it withstands cold but stops growing during the cold season. It restarts in spring, a little later than elodea.
