Does anyone know anything about these? I was thinking of putting them under my sand substrate since they seem like theyd be easier to separate from it, i dont know how much of a mess they make and i kind of want to keep my sand looking clean. Also, should I use a fertilizer water additive along with them? I would also appreciate some tips on this subject. Thank you!
