Crypt tank

[Ross satchell]

Hi i have a 25l dennerle cube
25l x 25w x 30h
I want to put on a Acadia classica 18cm 6w. Will it grow crypt parva, crypt nevilli and crypt crispatula.

Should be okay!
These Crypts grow very slowly without a carbon source, especially Crypt sp Parva!

I've got a little area (carpeted) with Crypt parva in my low tech. It stays alive but is the slowest growing plant in the tank, even Java fern is faster. Looking at it for 2 years now and i realy have to look at 2 year old pictures to recognize it realy did grow and propagate a bit. If i have to rely on memory i wouldn't realy see the difference. So if you are planning a Parva carpet without adding co2, make sure you put in a lot from the start and don't expect it to propagate and run very soon. Tho i did read low tech threads with faster and larger growing parva than mine. It might be soil type or water hardness or who knows what related, i don't know. So it is very hard to say yes or no. It depends and i have no clue on what.
