still don't know,i did check the ammo,ph and nitrite and they'r all good.
my blue ram looks fine even better than he did at the lfs,and there are 3 very young clown loaches that are doing even better.*sigh*who knows,this weekend i'm taking a sample of my water to the lfs to see what they come up with,but maybe not since all the other fish are doing so well .anyway thanx for asking
