Java Moss Issue?

Cdbaby123

I set up my new 45 gallon planted tank on Thursday when my plants came in. So far they look good except for my dwarf lily bulb which is still floating more than 60 hours later, and not it looks like my Java Moss might be turning brown. I am doing a fishless cycle. Should I be concerned about the moss or will it be OK once the water parameters are good? Yesterday afternoon they were.

PH- 7.6

Ammonia 2

Nitrites 0

Nitrates 5

KH 50

GH 50

Water temp is 79.3 and I am using the Fluval 3.0 plant light. Set on the Auto, Sunrise 2 hours daylight 8 hours sunset 2 hours moon light 4 hours.

I am using easy green fertilizer and tabs in the plants in the gravel. Last time I put the easy green in was thursday because the bottle says to use once a week...
This tank does not have Co2 hooked up to it.

I am new to this so any advice would be appreciated.

From what I've seen with my jarva moss when I cut lumps out the inner part is brown and stays that way until the light dose its job and in no time its up and running green again, this plus a change of water conditions could be what you're experiencing, with the ferts you've got in there I'm sure it'll bounce back

How many hours do you leave the light turned on?

Here is my experience in keeping java moss. Some of my java moss is green and some are yellowish-dark-green with a brown stem. The first time I bought java moss, they turned brown and died in my tank, this is due to the warm temperature of the tank because I left my LED lights on for like 14 hours or more, which is a bad idea, and my tank temperature, in general, was around 90 to 94 degrees Fahrenheit and this is not just due to the heat produced by lighting but It's also due to the summer heat. This temperature range could kill java moss.

I just learned that leaving the LED that long could possibly burn plants in the tank. What I did now is that I limit the hours of lighting my tank to around 7-9 hours and it seems that the new java moss is not turning brown like the first that I bought. And thankfully, summer is over, now, the temperature of my tank is around 86 to 87 F. (which is still warm but at least it does not kill my java moss).

I see, then the temperature is not the problem. I think the moss would probably survive as long as the water parameters are maintained and like riched said, just let the light do its job. The lower temperature is what I wanted to achieve, that's why Im just about to use an electric fan to at least cool the tank.

It is just melting due to the change of environment. Keep fertilizing and be patient and it will start to grow back. Mine turned almost completely brown after I put it in and a couple weeks later I noticed it had new green tips growing.

Your temp is fine for cycling. Bacteria grows better at higher temps. Java moss is kind of hinky like that. It just totally dies in my tank where others flourish.

Some "Underwater Gardeners" have "Great" success others not so much. When I first started I wanted to try plants. Java moss was mentioned as "Easy".
I had the same issue it did not look good. But... after the initial melt, acclimating to my water and about 6 weeks, 8 hours a day light and liquid ferts. It took off.

Good Luck!

relatable, I also thought Java moss was easy-plant for beginners but It wasn't really that easy.

Java moss was the one thing that gave me loads of grief.

As most of the previous posts stated the moss does turn brownish and look like it's melting before it picks back up. My first try was a failure. I set it up and it just died. And I think it's because the tank was still uncycled and I kept messing with the moss trying to see if I did something wrong. I also think I did not attach it correctly. I used glue but did not cut up the moss or trim it once done attaching.

Later I saw that cutting and trimming is not entirely necessary but will stimulate growth at the cutting point. I also saw many people saying that once you've attached the moss, you should let it do its thing. So I reattached new moss on the drift wood and now that moss is thriving big time.

This is on the 19th of May 2021:

As you can see it looks like death on the first pic and now it's really thriving. It is definitely a slow grower. I use CO2, have high lighting and dose ferts and despite that it's still kinda growing in. I know the tank looks messy but it's a shrimp tank so that's what I want :)

It's possible that it is getting too much light. You can try putting some in a shadier part of the tank and see if it turns greener there over a day or two. If not, it is probably not an issue with the light.

You can try floating plants to provide shades for the java moss. if you are keeping gouramis, don't buy frogbits, but buy Savinia or water lettuce instead

Java moss ime takes a long time to adjust, you will need patience with it. I find it can take 2-3 months before it starts to grow in my tanks after replanting, moving it around, etc. Once it takes a hold though it does pretty nice.
