I just put in that Zoo Med Eco Earth compressed coconut fiber into all of my cages. Its the stuff you put into water and it expands into about 8L of substrate per brick. I noticed after about a day, it is starting to have a smell to it. It is not an incredibly bad smell but you notice it. For those of you who use this, or those who mix water into substrate, is this normal or is this a sign that it is stagnant. Thanks.
