need plant advice

[Kate Breimayer <kate@munat.com>]

Hi,
I have a recurring problem with my java ferns. The leaves turn pale and 
finally white periodically. I am using flourish 2X a week, and it seems 
to happen periodically. The flourish bottle is not very specific about 
dosing, and maybe I am underdoing it? Using 1 ml in a 26 gallon and in a 
45, and about half a mil in the 10 gallon tanks. Some have CO2, others 
don't, some have compact flourescent, others standard flourescent. I 
have tested the water and these tanks have no measurable amount of 
ammonia or nitrate (which is better than I can say for the water 
straight out of the tap). I am not seeing loss of color of non java 
ferns, and the fact that they sometimes recover makes me think they are 
not burned by the lights, but maybe this is the case? Anyone else seen this?
Thanks,
Kate
