i helped my friend set up a ten gallon planted tank with eco complete as the substrate. he wants the top of the sub. to be completely covered in baby tears, or sumthing like it. hes bought two rocks from the store that had baby tears on them. the pushed the first rock into the substrate leaving the baby-teared part right along the surface of the floor of the tank. the second one he ripped off the rock and smushed into the surface of the substrate. i feel like this isnt going to spread fast enough though. how can he get a carpet like that??
