I've been having some problem lately with my leathers. I have a rock with 2 toadstool, the one is 5" diameter and doing great, the little one is 1" diameter and slowly doing worse, the outside turns white and dissolved slowly. I don't have a pic of that
The other 2 seem to be not so happy either. The one has a little hole that is growing, it has black around the edge of the hole and the leather seems to be shrinking.
The other one is kinda white/fuzzy around the base and doesn't expand like ti was at my LFS
Another leather I've had for months and months is dissolving as well.
are a little low around 3meq/l and 375Ca, amonia/nitrite 0 and nitrate <5
I"m very troubled by this
