Plant's look to be Ludwigia,Anacharis,Hair grass,and Sword plant of some type.(sword plant' s too big for jar's + nutrient hog's).
Walstad method requires few water changes rather than daily.
Piece of cuttlebone used in parakeet cages can also work for calcium for shrimp(moulting).
Nothing wrong with just plain top soil IME.
