My java moss looks brown, what could simply turn wrong? Help please!

My java moss looks brown, what could simply turn wrong??
Does anybody know??

My Tank Description

Volume : 30 Litre
Substrate : 2 inch of amazonia (medium)
1 inch of sand (medium coarse)
Other Inhabitin: Riccia fluitans
Cabomba
Ranunculus limosella
Riccia "Dwarf"
Cherry Shrimp
CO2 System : Nutrafin CO2 Natural System

Note : I see these microcrustesean (Water flea) inhabit my java moses clump,are they eating it?

Hi!
I've got some problem in my new tank while the same moss in the old one looks well.
I think there's some problem with micro-nutrients but not shure.

I'll wait with you for any help :-)

I don't the water fleas are eating the java moss.

Java moss can withstand a wide range of environmental conditions, but does well in low/medium light, cooler water (70-72 degrees), and a decent amount of water circulation. Also, it loves to absorb iron and micronutrients as Rudi hit on above.

The browning parts will probably not recover (some parts will) to the beautiful plant it may have been. I would trim off most of the dead parts off, leave it floating closer to the light, and add some micros in your tank.

I don't think it needs more micros... I think I dosed too much Iron...
Near the browning of moss there is also a little invasion of green algae... this may be too much Iron.
I've read somewhere that too much Iron can bronze leafs so I think it should browning moss (???). Is it possible???

[John N.]

Adding micros and iron have always led to good growth of java moss in my tanks. Sure, too much nutrients can lead to algae growth and thereby hinder plant growth. I used to add Seachem Iron regularly in large amounts to bring out the reds of my plants. The tank also contained java moss which did not turn brown.

Looking at the picture, I think the browning of moss in this case is more likely due to a combination of low light, inadequate nutrients, and maybe water temperature. Farizal are you dosing any fertilizers, what is your lighting and how are your other plants doing?

-John N.

[papillon]

as said a good water circulation is a must plus try increasing your co2 in the tank, how's your temp and lights?

if you think you over do your iron, all you have to do is water change about 30%....

goodluck and happy plant keeping!

Hi,
Check again water first, I think two items make java become brown
- Wrong light, over 10,000k is ok
- Temperature: too high
I think light is a problem. I use to be the same case.
p/s: sorry if my E not good. Thanks

is 24 °C too high ??? (This is the temperature in my tank).

10000 k ?? I never use lamps so high in °K but in my other tank mosses are ok...

[papillon]

you're water temp is fine at 24degrees, you can use a 6500k light, a 10,000K is to much for plants... this is use for reef tanks

Well!! :-) For a while I've think I was wrong...

I'm still tinking in my case there is too much Iron... now I've stop dosing it for some days...waiting for...

This is not true. In most instances, lights with a K rating over 10,000 are not used in planted tanks.

Plenty of people use 10,000K bulbs and have absolutely no issues with plant growth; they're usually used in conjunction with another, lower K bulb, however. As a matter of fact I had a discussion a while back with a gentleman who use an 18,000K bulb with spectacular results...many other freshwater aquarists use actinics to make the coloration of certain fish "pop."

The point is that lighting has value in the aquarium not only for plant growth, but for the tank's overall aesthetic as well. By using bulbs with different Kelvin ratings together, you can create a "customized" lighting scheme that best accentuates your particular plants and fish. Check out this link for further explanation and absolutely excellent pictures of different lamp combinations over tanks and their different effects.

I'm using 10KK MH Bulbs combined with 6.500K MH and have to say that all plants in my tank are just fine and satisfied with the lighing, as well as Java moss. It would be necessary to have all relevant facts regarding water chemistry, fertilization and lighting in order to find out what could be an eventual problem regarding the brownish of Java.

In short, do not agree that the problem is linked to TE (Micros) as it more likely indicates on extreme deficiency of some Macro element or completely inadequate conditions in the tank... I cannot be sure 100% but therefore, it could be very useful if you could inform about current status of the other plant species you have in the same tank.

In my case may be You're right. In last two days I discovered some pinholes in some plants and a little yellowing of Cardamine leaves...could be Potassium deficiency...

[Fikus]

K deficiency shows first on the old leaves, that could turn uniform yellow and some pinholes could appear and slowly enlarge in the leaves. Chlorosis caused by Potassium deficiency is irreversible, so as John already mentioned above, the browning (chlorotic) parts of Moss will probably not recover so would be the best to trim them off. Accordingly, try to add some K2SO4 in order to see what will happen with Cardamine and Java moss, and the rest of your plants in the tank.

Just a little update...
Dosing daily 1mg/l of KHCO3 the moss seems to recover (slowly).
I choose KHCO3 instead of K2SO4 because my substrate (akadama) is still droping the KH. So it seems that I solved two problems in a while.
