Hi all, I'm in the process of setting up a new tank, I ordered some new plants from the LFS, :lol: When they arrived I put them into a holding tank till required. Tank was newly filled with 80% rain water 20%tap, up to temp and a little leaf plus for good luck. No gravel and an air stone. pH around 7, kH around 3. Plants were mainly Crypts, various types. Within a day the leaves were melting, hopefully they will recover now planted in the new tank, but what would have looked green and lucious now looks barron and stumps. What Happened????? How can I prevent this happening again???
