Help me asap

Strange, since red/brownish water is usually caused by materials making the water more acid,
like peat, leaves or types of woods for example.

Maybe it is the eco-earth turning you're water brown.
But dying fishes?
What else did you use in you're enclosure?

I'm afraid you'll need to give us more information than this, preferably a picture of the terrarium and the water. Eco-earth can dye the water to an extreme extent, but in order for that to happen, it needs to be in direct contact with the water. Are you keeping Eco-Earth in the water area or something like that?

well i got a foam wall with eco-earth stuck on it. and i have a piece of drift wood to look like a tree that has a waterfall that pulls water from the water area to drop back into the water area.
i used coco husk/eco-earth/drift wood

I think it's just because of you're waterfall over the wood combined with the cocopeat.
Shouldn't be a problem.
The water in all of my tanks have a brown/reddish coloration,
nothing wrong with that.

You might use filtration over activated carbon if the color bothers you.
But you will need a filter to do so.

Was the foam completely fixed before you put water in by the way?
Otherwise i have no idea why the fishes would die on you.

I think it's strange that you're water test said that the water hardness is to high,
since nothing you used should cause this, the materials have the property to lower the hardness.

Perhaps wesleybrouwer help you enough, but just so you know, when you upload a picture, you need to put a direct link to the actual picture within the IMG-tags (and not just the directory of where the picture is located at your computer). Imgur.com the best upload site, in my opinion.

the red water happen also in my tree frog tank but over time the water became clear

when i change the water its clear for about a week and then it becomes red/brown again.
