All the crypts melted after 3-4 months. After a cleanup and 
change of water, the plants put out new leaves. No permanent 

The dissolved solids build up, I use a TDS (total dissolved 
solids) meter to check tanks that I may have forgotten to 
do the weekly change.

I have seen tanks/fish doing well even up to 1500 mg/L, 
suprisingly green cabomba grows very well in these conditions!
Needs calcium + nitrates for fast growth..
