My tap water has a gh
that is higher then 12 but my freshwater aquarium water has a gh
of one or two drops. I am trying to do a fishless cycle and I am afraid the low gh
could stall it. Also, it is strange that the gh
from the tap is high and in the tank it so low, it is the same water. I do have some rocks in the tank but that should raise gh
I thought. Any ideas?
