Sunyang: If you mean the CRS tank, I have a sponge in the intake and fluval biomedia in there mostly, there is also a 1/2 coarse sponge sheet. There is frogbit and Utricularia foliosa floating inside in the media compartment and the other plants are planted in the "cascade" only... It's mostly Xmas moss.
Oh, there is about a table spoon of activated carbon in a mesh baggy right before everything else. (I've observed clearer water using this)
A heavily planted shrimp tank is possible!
