Water too hard for Amazon Sword?
In my Eclipse 6, I've got an amazon sword planted has some brown spots and holes in a few of the leaves and I've had to prune a couple of dead leaves. The hornwort that's also in the tank does quite well.
A couple of weeks ago I got test kits (the AP Master and the AP hardness kits) and the water parameters were good except the nitrates were quite high (a couple of water changes fixed that). Currently the paramters are:
Ammonia: 0
Nitrite: 0
Nitrate: 20
dGH: 11
dKH: 4
pH: 7.4 - 7.6
Could the hardness be to blame for the problems with the sword? The light is switched on about 12 hours a day (I dont recall the wattage right now).
