Ok, I may be asking a question that has been covered many times before and thus redundent, but if one has a particular plant, in this case, broad leafed water sprite, or Pteratopteris cornuta, and the leaves yellow and melt with little to no new growth, and they are floating, thus receiving atmospheric Co2, and all my other plants submersed are doing fine, is it poss. that I could use some form or specific concentration of lime to spur the growth. Also worth mentioning is I have other floating plants multiplying just fine.
This is how I am thinking,..........if one has a yard of grass and it is yellowing, lime applied will green it up.
I just am not sure what this plant needs or doesn't need that I either do or do not have in the water for it. I am presuming it is the water. Not sure though. Just makes sense to me.
p.h. runs about 7.2, hardness around 17.
As I said all other plants doing fine.
Lights are compact Fl. daylights.
Fishroom has no natural sunlight.
Advice please !
Thanks so much !
