That's good avice, thank you, I'll remember that!I've found that if you take a flat blade screwdriver and a hammer and split the block along the edge into thinner wafers it takes far less water and can be reconstituted sill fairly dry. It takes a little work adding water little by little and breaking it up by hand until the fiber is all separated but doing it this way I can use it immediately even for my most arid loving T's.
yes the bag trick work wondersI buy the bricks, drop them in a plastic trash bag that is inside a small wastebasket. Soak the whole thing, prep the cages a couple of days before I get the T. Stir it up occasionally to let the rest in the bag dry out. Then it's expanded and ready if I need more, and I can just close up the trash bag as needed. Half a brick can be put in a gallon ziptop bag and expanded, then left not-quite closed to dry out slowly if needed. It's messy a bit, but better than some of the other substrates.
