Yes I too have this problem. I can't grow java fern in any of my tanks. It all turns black and dies. I bought 100$ worth of java fern, over 4 square feet of the stuff and 1 year later I now have 3 meager rhizomes about 1 inch long each and dieing. Survivors they are indeed, but dieing, yes.

Since then, my java ferns grow much nicer looker with much less black sections. (I also don't get BBA as much, either, since i started using activated carbon.)

Maybe i'm just unlucky with my tap water and something is in it that my java ferns don't like... For me activated carbon did the trick. I'm sure there are plenty of people w/ great water from the tap that don't have this problem (of okay tap water quality) and grow great java ferns with no problem, but i'm wondering if anyone has noticed this as well... has anyone added activated carbon or switched to a purified water source like RO/DI and noticed a change in their java ferns growth?
I grow it outside in a stock 70 gallon tank with endlers and guppies and it grows like weeds in hard water attached to wood , no filter (I change 1/4 to 1/2 water volume weekly)

It seems to grow very well in sunlight . I am trying some inside now but don't know how that will work out.

I did read once somewhere the Java Fern is sensitive to chlorine. I don’t remember where that was exactly so take it with a grain of salt.

what about light? java fern are low light and tend to like cooler water i have found. java fern trident does better than wendlov or common and i also have a narrow leaf that has done pretty well. my tanks tend to stay no warmer than 70 and are alllow light

the package should have told you. i know i have 10 and 15 watt cfl bulbs but they are equal to a lot stronger like 30 to 50 watt i think. some plants just dont like warm water and some dont like cold. i know mosses dont like warm water either. i dont tend to do to well with common java but my trident loves what ever i do cause it grows like a weed

As long as you have the CO2 and nutrients to back it up, java fern does fine in higher light. It's known as a low light plant because it can still grow in low light not because it requires low light.

I'm not sure it prefers cooler temps either. It's really not a very demanding plant and should do well if other plants in your tank are also, but it seems like there are times when there's just that one plant that gives you trouble

What is your water like? Java fern needs more than flourish in most water. If I don't feed it goes down hill fast.

The reason I got the java fern was because I read it was easy to maintain...and its becoming a lot harder than I thought....I want to keep this a lower cost tank..I don't wanna spend money on a whole bunch of ferts..the ferns are the only plant that is not doing so hot...I am keeping it simple with the flourish, the lights I have, and DIY c02!
