Rewcolee1 Posted April 3, 2023 Share Posted April 3, 2023 My Java ferns a month ago all looked fantastic. I have changed nothing and now they ALL look like this. I dose Easy Green 2x a week and also use Root Tabs. Any thoughts or suggestions would be amazing. Link to comment Share on other sites More sharing options...
Ninjoma Posted April 3, 2023 Share Posted April 3, 2023 (edited) Is the tank or the substrate relatively new? If so it could be brown diatom algae. You can either wait it out and it will go away on its own or you can add something like otos that will eat it. Edit: also are the rhizomes above the substrate?

I have noticed the fish moving around the stones have covered the rhizomes. The one that is definitely not buried looks the same. Link to comment Share on other sites More sharing options...

DaveO Posted April 4, 2023 Share Posted April 4, 2023 Try Seachem Flourish Potassium. Those ferns like extra potassium. Also, do raise that one up out of the substrate. That will rot the rhizome. 2 1 Link to comment Share on other sites More sharing options...
ccurtis Posted April 4, 2023 Share Posted April 4, 2023 Likely a potassium deficiency. Java ferns like a lot of potassium. Mine looked like that for a while. I started dosing API Leaf Zone which is mostly soluble potash or potassium with my east green. It took a few weeks, but they perked right up when I added the leaf zone. Good Luck Link to comment Share on other sites More sharing options...
Rewcolee1 Posted April 4, 2023 Author Share Posted April 4, 2023 I ordered some Flourish Potassium today. I’ve uncovered the rhizome as well. Hope it works and thanks for the feedback all! 1 Link to comment Share on other sites More sharing options...
PineSong Posted April 5, 2023 Share Posted April 5, 2023 My similar problem with java ferns was solved by starting Flourish potassium. In addition to starting the potassium, I cut off the most damaged leaves, up to 1/3 of the total leaves, in order to allow the plants to use their energy for making new leaves rather than maintaining or repairing old damaged ones. As a side effect of adding the potassium, Java moss that had been MIA for many months resurrected itself and has also grown lush.

Before: After: I did think about cutting off the dead or dying leaves. I’ll definitely do that now once the Potassium arrives tomorrow. 1 Link to comment Share on other sites More sharing options...
Monkeypoint Posted April 6, 2023 Share Posted April 6, 2023 I'm having the same issue. Buying some Potassium Flourish now! Link to comment Share on other sites More sharing options...
Darax Posted April 6, 2023 Share Posted April 6, 2023 (edited) Plus one on potassium suppliments. I dose a little bit twice a week, and recently started using seachem flourish instead of easy green. (my tanks are well stocked, so the nitrogen in easy green isn't necessary ) Here's an old and recent shot, tank does have CO2. Edited April 6, 2023 by Darax Add old shot of tank.
