RE: pale sword leaves



This happens on a regular basis to the swords in my Discus Tank because of
the sterile acidic water. I dose with PMDD mixed with double the K2SO4 
and they firm up both in texture and color after a couple of weeks. Iron
could be the deficient mineral but I didn't see any improvement until I
increased the potassium levels.
