I've just purchased several cryptocoryne balansae, 2 clumps of plants were in great condition leaves around 30cm looked great aswell as another smaller plant.On planting after around a day or so the leaves started to melt which I've read can be the case (crypt melt).but on researching more on it it looks like I had planted to deep covering the crown.is this true as the 3 other types of crypt in my tank have all been planted the same but never experienced any melting.so I pulled them out to try to replant with crown showing and it seems I've just made a bigger mess. Alot of the tall flowing leaves have fallen off and now looks horrendous. Any advice on what to do , replant as it was ,leave and let it do it's own thing or anything else.
