Hi! My aquarium has two java ferns, an anubias congensis (I think that's what it is), and small bit of hair grass. I get 1.85 bubbles per a second from my bubble counter for my diy CO2 18.5 bubbles/10 seconds = 1.85 bubbles. My light is high, 10K per a bulb. I think each bulb has 10 watts...

Ok, so I have a Java Fern (wendelov?) that's been in my tank for a week now. Lots of the leaves are turning black, and I can't figure out why. It seemed to be doing fine earlier. Also, all my hairgrass seems to be turning a clear/brown. Its all in my 10g, and the hairgrass has been in there...
