How to Use Egeria Densa Aquarium Plant
This egeria densa aquarium plant is
extremely versatile in how it can be used.
Push the stems gently into fine sand or
gravel substrate keeping leaves above the
substrate at all times. Or simply leave it
floating freely in the water column — it
grows equally well either way.
Under good lighting this egeria densa
aquarium plant grows very rapidly and may
need trimming every 2 to 3 weeks. Simply
trim with sharp scissors and replant the
cuttings by pushing them back into the
substrate — each cutting becomes a new
plant and rapidly produces new growth.
Egeria Densa as a Natural Algae Controller
One of the most valuable uses of this
egeria densa aquarium plant is as a natural
algae controller. By growing so rapidly,
Egeria Densa absorbs large quantities of
the dissolved nutrients that algae needs
to grow — effectively starving algae out
of your tank without any chemical
treatments or interventions.
In a new tank or a tank struggling with
algae, adding a generous amount of this
egeria densa aquarium plant can make a
dramatic and visible difference to water
clarity and algae growth within just a
few weeks of introduction.
One Important Note
Egeria Densa is sensitive to Excel liquid
carbon and high doses of glutaraldehyde-based
fertilisers. These can cause the leaves to
melt rapidly. If you use liquid carbon
supplements in your tank, use very small
doses and monitor the plant carefully for
any signs of adverse reaction.
