Vallisneria Posted September 28, 2006 Report Share Posted September 28, 2006 I bought some Elodea aka anacharis on monday and it seems to be turning translucent. I have them floating in a bare bottom 10g with a 13w CF bulb. I dose Flourish Excel, flourish trace, flourish potassium, and KNO3 and phosphate(same thing I do to my other planted tanks). Why are they melting? I thought these were supposed to be a super easy plant to grow? Quote Link to comment Share on other sites More sharing options...
Toirtis Posted September 28, 2006 Report Share Posted September 28, 2006 What is your pH? Elodea like alkaline, mineral-laden water. Quote Link to comment Share on other sites More sharing options...
Vallisneria Posted September 28, 2006 Author Report Share Posted September 28, 2006 Just regular edmonton tap, ph 7.8-8.0ish I believe Quote Link to comment Share on other sites More sharing options...
Toirtis Posted September 28, 2006 Report Share Posted September 28, 2006 Weird, I dunno....with mine, so long as there is good light and I keep up with water-changes, the stuff grows like crazy...never had one melt on me except in acidic water.

Vallisneria Posted September 28, 2006 Author Report Share Posted September 28, 2006 I had bought some a few months ago too and the same thing happened. The leaves went clear and the plant kind of fell apart. Quote Link to comment Share on other sites More sharing options...
Ichthyosporidium Posted September 29, 2006 Report Share Posted September 29, 2006 Is this Elodea canadensis? If so, what is the temperature of your aquarium? Quote Link to comment Share on other sites More sharing options...
Qattarra Posted September 29, 2006 Report Share Posted September 29, 2006 http://www.wetwebmedia.com/PlantedTksSubWebIndex/elodea.htm According to this site, it is a cold water plant. Quote Link to comment Share on other sites More sharing options...
Vallisneria Posted September 29, 2006 Author Report Share Posted September 29, 2006 So what temp should I have the tank at? I think right now its about 78*ish I have Endlers in the tank, can they take lower temps? Quote Link to comment Share on other sites More sharing options...
jvision Posted September 29, 2006 Report Share Posted September 29, 2006 Yeah, they should be fine even down to the lower 70s. Try it at 74 for a bit. Quote Link to comment Share on other sites More sharing options...
Vallisneria Posted September 29, 2006 Author Report Share Posted September 29, 2006 OK I"ll test out a lower temp and see if that helps. Thanks Quote Link to comment Share on other sites More sharing options...
Toirtis Posted September 29, 2006 Report Share Posted September 29, 2006 My E. densa grows great at 76ºF-80ºF, but I would suspect that E. canadensis would be best a few more cool. Quote Link to comment Share on other sites More sharing options...
Vallisneria Posted September 29, 2006 Author Report Share Posted September 29, 2006 How can you tell the difference between the 2 species? edit- I found this site http://www.ecy.wa.gov/programs/wq/plants/native/elodea.html and it says American waterweed is usually fairly easy to distinguish from its more notorious relatives, like Brazilian elodea and hydrilla. All of them have leaves in whorls around the stem. However, American waterweed has three leaves per whorl, whereas hydrilla and Brazilian elodea almost always have more than three leaves per whorl. Brazilian elodea is also a much larger, bushy plant with longer leaves. My plant has 4 leaves per leave segment/ whorl, so I guess its Elodea densa.

Toirtis Posted September 29, 2006 Report Share Posted September 29, 2006 Egeria densa has more leaves per whorl (3-5 as opposed to 2-3), and has larger leaves (2cm+ versus <1cm). Quote Link to comment Share on other sites More sharing options...
