OK, I finaly finished planting my vivarium and it looks great! One problem though, the water won't stay clear, it becomes a darker tea color. The water is not dirty, it is clear but colored. You can easily see thru it, similar to a light color tea. I know that this is because the water runs through the dirt, but I have a decent gravel layer too. My question is first can I somehow unstain the water? Second if I can't unstain the water, is this ok for the frogs since they can get into the water? Thanks to everyone for your help!
