That lighting level is just too low. Rooted anubias and java ferns will work much better than elodea.
Yes it will grow emersed, but the lighting doesn't really change much either. There is also a very easy thing you can do... cut the plant. Bacopa can be cut in half, and placed in the substrate and both pieces will grow.BlackTopKing;1039936;1039936 said:Not trying to derail the thread,
wyldfya; but dont Bacopa caroliniana emerge...grow out of the water ?
Just wanted to know if I was right...I thought about getting some but the LFS said they would be a problem once it broke the surface and needed external lighting- that the leave change-under water part is aquatic but not the top part....Or am I wrong?
