Re: java fern and light

Hi Penny,

I don't think it's a lighting problem. I have nearly 6 watts per gallon and
my java (regular and windelov are very very happy). Something might be
wrong, but I would not look at the light... Also consider leaving the leaves
with black spots for a while. Sometimes java gets ugly then new growth
sprouts from spores. It might just be a phase you have to get through,
especially in a relatively new environ.

FWIW Robin
