Has anyone had success in NPTs with Rotala wallichi? I've found I can order it, but I don't want to kill it, and the Plant Finder says it requires added CO2.
Is generally such a requirement a no-go for keeping plants in NPT, in your experience?
Typically yes. That is one that is known to be hit or miss for your tank. I have yet to try it but definately want too someday. From what I have read it is like Patanal, where some have the conditions for it some dont.
Benjamin, that is a beautiful plant! When you do try please keep us posted on the progress!
Tanta, thank you. That's great to knew. I think as with all plants there's usually subtleties and maybe some dose of luck involved. There are so many factors in ours tanks! The water, the light, the nutrient load,...
Maybe I'll try later on if things go well with other plants
I am currently growing Rotala macrandra successfully in my 4-gal NPT. It isn't super red like I've seen in some online photos but its growth is giving me a lot of confidence to try other plants that supposedly require CO2 injection.
I would say give the Rotala wallichi a shot. I probably will for my next tank
@ItsDubC : nice to know that!! how many watts/gallon of light do u use? Did u plant macrandra in initial set up or after the tank mature? i still have r. macrandra but in DIY CO2 injected tank, they seems to grow healthy there, but the tank has been mature for almost a year when i planted it. i wonder wether it is the CO2 or the maturity of the tank. because i red that for r. macrandra to thrive they need almost zero level of nitrit in water column
ItsDubc, thanks so much for the info. I think that's a very interesting field. But I think I'll wait as I'm still starting the tank - but I'll probably try in a few months if all goes well.
I'm also interested in the specs of your aquarium. I bet no two NPT's are really alike - there are so many factors!
CO2 plants (Rotala Wallichii) in NPT?
