Care for Java Fern - Black Spots on Java Fern

[@stewartrood3633]

At last I now know why my java ferns are turning black. Cheers!

[@nicoletiana]

My husband just gifted me Java fern for my 15 gallon fish tank and i'm so excited to learn about this plant and see it thrive!!!

[@Les-OZZYTHEOSCAR]

I love java fern but it has never done well. I've looked at loads and loads of videos on java fern, and all they keep saying is how easy it is. I've asked many times why it keeps dying to many different people, and nobody has ever said anything about potassium . You are the most informative video I've found on the internet so thankyou. I actually do dose ferts and specifically potassium , so I should be on the right track now, but I actually know the reason for failure now due to you. Great video and thanks

[@ruidadgmailcanada8508]

If you’re buying them they are many smaller plants bundled and tied with black thread. That thread needs to be gently removed it restricts the roots and it won’t thrive. Now you have a few more plants once it’s unbundled.

[@andrealibby1788]

This is so helpful, thank you!

[@cstatum1]

The aquarium co-op easy green has just over 9% potash, plus everything else most plants need. I might be an option if you only want to use one fertilizer. Great video. I was having this problem and had no idea what it was from until I researched and then I came across your video to, thought I'd let you know about the easy green.

[@MsDF936]

I use Easy Green and I'm having this issue :(

[@davezzz7664]

same for me. I use easy green, but my java ferns are covered with black dots. All my other plants look normal.@@MsDF936

[@Hren_C]

@@MsDF936 same. Have you found any solution?

[@Carolina-ql1kn]

Same. I already dose Easy Green and the first few weeks the Java fern looked nice, but currently it looks ugly. I'm now trying to grow it emersed since it was going to die underwater anyway. I suppose I needed to add Flourish Potassium also? :/ what other alternatives are there?

Any updates on the Java fern rehab project?? Id be curious to know how it's going.

[@JayJay-cl2ot]

any updates on java fern? Did the black dots disappear? you mentioned that you will keep it updated, but I didnt find any videos related to that topic. Also, there's another youtuber guru who owns an entire gallery of fish tank, he ONLY use api leaf zone for all his planted aquariums, they all turn out great looking.

[@S.cgb_2017]

Thanks!! This is my third time trying to grow java fern in my tank. I was so puzzled because it is listed as a super easy plant and I could not figure out what was missing because mine just kept wilting away... I bought the Leaf Zone and will try it for sure :).

[@TropicalFishGuy]

Something to be aware of is not to bury the stem(rhizomes). Otherwise let us know how the fertilizer works out.

Did the Leaf Zone work for you?

Do you dose the tank with flourish and leaf zone different, or can you dose with both the same day and it doesn't matter

[@TropicalFishGuy]

I don’t think it matters but I dose in different days.

Thank you so much my camboba was thriving but my fern was dying I'm gonna try use the API leaf zone API is a great brand

Late reply but. API leaf zone is just full with Pottasium and Iron. Not an all in one solution. I'd recommend Aquarium Co-op Easy green.

[@happygoesalwayslucky5966]

​@@TropicalFishGuyactually drying the banana peels and soaking them in water for a few days and then dosing with the liquid part after filtering the peels out, can work for potassium deficiency as well as calcium, magnesium and phosphorus.

[@sanjanrkashyap8889]

​​@@happygoesalwayslucky5966nope I did that and read some forums on the specific topic, after doing some research did I find out that banana peels have minute amount of potassium, instead there is an element that has the same properties of potassium but it's not.. it just has the same properties and isn't gonna work out like you've said hope this helps

[@simoncushing1048]

Good flow, temp 23c, you do need Co2 have you read the Tom Barr report? Spotting is due to poor Co2 and circulation.

[@holyeppie]

Hello if Im gonna buy and use the Seachem Potassium one can I use it on the same day as my regular fertilizer? I usually add regular fertilizer once per week after a water change. Or would you recommend having some time in between? Thanks for the information so far really is a helpful video

My java ferns look exactly like the ferns in your video. I’ve not given it any fertilizer or potassium. The java ferns keep growing and propagating (from 8 to 15 plants), crypto spiralis and banana plants thriving, Mexican oak leaf growing like crazy, some algae here and there, the fish are great and the mystery snails are multiplying. For me, no need to add anything and disrupt the ecosystem.

I have struggled so much with my java ferns and mine have same symptoms but have progressed much more than yours. Is it possible to get an update now 4 month after this video. Have your method helped the java fern? Good video 👍🏻

Thanks. Yes it can be hard. Usually the issue is that the light is on too long. I keep my lights on for about 6 hours now. Java Fern don't like intense light and definitely not for long periods of time. Mine are doing fine. Hope this helps.

@@TropicalFishGuy i have played around with the light as well as the java fern in the back corner of the aquarium is doing much better so don't think it is just potassium deficiency.

I don’t know why they say things like Java fern and subwassertang are easy I’ve tried 3 times and so far I’ve not been able to grow either they turn brown and start to disintegrate leaving behind just the midrib of the frond. They always get black spots and new growth will die and it turns to a bit mess. And the subwassertang is just a failure to do anything except get devoured by my Inca snail even tho I’m feeding his his own food which he happily eats he

[@TropicalFishGuy]

Yes, I see where you are coming from. I have had some problems with Java fern and it is a bit picky. I've never tried subwassertang. Thanks for your insight and sharing your experiences.

[@Iamaguienapig]

My plants in my 5 gallon tank are melting. It’s 25c temp, fully cycled, one betta, black water. New set up but media used from a 5 year old fully established tank. I dose a standard fert once a week, could it be a potassium deficiency?

[@jacobdavison7506]

do you use co2?

[@TropicalFishGuy]

This is pretty common. Depending on the type of plants you get, they will melt no matter what you do. For example sword plants will usually melt all the way down to the stub and them come back. This is because a lot of the plants we buy are grown with the leaves out of the water. When they get into our tanks, they have to convert to their water form. But this is not applicable to all plants and could be something completely different. What kind of plants are melting on you?

[@WhatIsMisophonia]

I'm coming to the conclusion that liquid fertilizers are a ripoff. Why do they need to be liquid when you can get powders for a similar price for the weight? Apparently with the liquids, you're mostly just paying for water. Is it so hard to mix your own? In the case of potassium, the aquarium stuff is all just potassium chloride or sulfate, or a combination. I just got an 8 oz. bottle of potassium chloride from a health food place for 7 bucks. Seriously people, stop letting yourselves get ripped off and take a little risk. "To provide potassium, you can use 'salt substitute', which is potassium chloride (KCI). If you add about 1/8 tsp to every 10 gal of tank water, you should get 10 ppm K, which is plenty" - Diana L. Walstad. 2012. Ecology of the Planted Aquarium. p.87. Actually, there are a lot of things sold as a salt substitute, so you're better off just running an internet search for 'potassium chloride powder'.
