when i change my substrate with in the next couple weeks Im going to switch from coconut husk bark to the coconut coir. I can buy a bag a the loose coconut fiber, which is the same as the bricks but its already expanded, now my concern is since you need to put the brick in water, do i need to worry about it making the substrate to moist and causing health problems for my tort? Now i know many people on here use it so i shouldnt worry so much, but i would love to hear that from the people who use it !
