As you can see in my aquarium profile i have a similar plant called dwarf water lettuce grows similarly just has more fluff and hairs and roots! and i have never seen a plant grow like that -_- hehe.
Hey, funnily enough I have just ordered some dwarf water lettuce from eBay and eagerly await it's arrival, so I'll have a mix of that and salvinia floating
love the floating plants!!
I have noticed that some of the roots are a tad brown, so a lack of nutrients could be a problem, but like I was telling Byron I am now dosing with flourish comprehensive twice a week so I'm guessing this will provide sufficient nutrients? Got quite a high bio load so the plants should use some of the ammonia. But I also have quite a lot of plants too.....
Is it worth looking into adding CO2? How hard is this and is it dangerous with a high bio load tank? Don't really know much about the CO2 game..
