Java Fern
I am having no luck growing Java Fern, the leaves having all turned
brown/black in the space of 2 weeks. The plants are attached to bog wood in the middle of the tank. Tank specs a PH 7 JBL pro co2 injector Nitrates @ 25ppm Leaf Zone added once per week 40 Gallon tank. Bright Lighting Other plants include amazon sword, elodea densa, rorippa aquatica, crypts, etc. These plants are all doing fine. The brown/black does not seem to be algae, it seems more like the leaves are just dying. Could it be that the lighting is too bright, or perhaps not enought nutrients? JFM |

JFM I have Java Fern in most of my 14 tanks and have noticed that those in low lighting are doing better than those in bright lights. I have a 77g with 120 watts of light and they grow well and then I have several 20's with a shop light 2. 40w bulbs, one cool white and one growlux and they don't do much of anything. Rick |

Leaf Zone added once per week
You don't say how much light you have, but if you really have bright lighting (3 wpg or more), Leaf Zone once a week is not enough. Leaf Zone contains only iron and potassium. You need a complete fertilizer, like Tropica Mastergrow or Seachem Flourish. And you'll probably need to add it more often than once a week. Even then, it can be hard to keep java fern healthy in a bright tank. It's not the light, it's the nutrients. It has a hard time competing against fast-growing stem plants for nutrients. I keep a separate tank for slow-growers like anubias, java fern, and java moss. It has moderate light and no CO2, but the plants grow like crazy. While ferns and mosses never do well in my high-light tank. Leigh http://www.fortunecity.com/lavender/halloween/881/ |

Not that I know what's really going on but...
Mine did the same thing and I thought it was dying. But for some reason (laziness?) I didn't remove it as it "died" and one day the brown leaves started sprouting babies. Now it's doing great and getting much bigger. My theory is that it doesn't like to change conditions but after dying back some it will adjust and come back. Can anyone tell me if this is the case?

Cris Many aquatic plants are grown with the foliage 'emersed' (out of water). Upon submersion, these leave will die, to be replaced with new leaves. Not saying this is the case here, but it's possible. |

With too much lighting I have that exact problem. Try providing some shading by using the taller plants to shadow it.
