Western Waterweed care guide
Western Waterweed (Elodea nuttallii) — medium light, 10-24 °C, pH 6-8, no CO2.
Overview
Western Waterweed (Elodea nuttallii) is an aquatic plant of the family Hydrocharitaceae, listed in the Aquairi knowledge base as a beginner-level species. It is typically grown under medium light and without obligatory CO2 injection on any substrate. Cold-tolerant elodea with thinner, more curled leaves than common Elodea canadensis. Excellent oxygenator and nutrient sponge for unheated tanks; can become weedy.
Taxonomy
- Family: Hydrocharitaceae
- Genus: Elodea
- Scientific name: Elodea nuttallii
Habitat
Elodea is a genus of submersed plants (Hydrocharitaceae) native to the Americas; the whorled-leaved stems are hardy and fast-growing and have become invasive weeds in many temperate regions. In the Aquairi knowledge base, populations associated with this form are recorded from North America.
Growth requirements
- Lighting: medium
- CO2: not required
- Temperature: 10-24 °C (50-75 °F)
- pH: 6-8
- GH: 4-18 °dGH
- Substrate: any
- Maximum height: 50 cm
- Growth rate: fast
- Recommended placement: background
Placement
A background or floating bush valued for rapid nutrient uptake and oxygenation; it tolerates cool water and grows with or without anchoring. In the Aquairi knowledge base this form is recommended for the background under medium light and without obligatory CO2 injection, using any substrate.
Propagation
Propagated by cuttings and fragmentation, with each stem segment readily rooting or continuing to grow while floating. Documented propagation techniques for this entry include: stem cuttings.
Common issues
Vigorous growth can crowd out slower plants and clog the tank; it should never be released to natural waters, where it is a serious invasive.
