Nitrate Spike and Crustaceans...
I noticed today that my rather large red hermit crab (about 2.5-3" long) has molted and shed his skin sometime either yesterday or today. I noticed it in pieces laying in a very bad location underneath some rock in a cave. Looks like the guy has actually tried to bury some of it under the live sand too. I also checked my perimeters today and was a little high on the Nitrate side of the house. Perimeters are as follows:
55 Gallon FOWLR
Nitrate near 25 PPm
So, my Nitrate level is a little elevated (and this after about a 15 gallon water change only a week ago). Could it be the shell pieces left over in the water from the molting causing this slight jump? Should I move my rocks and remove all the pieces, or leave them buried by the big crab? Just wondering, I'm new to the game but trying hard! Mind you now, I did top off my water with about 2 gallons BEFORE I found the molted carcass, thus stirring up the water slightly. This also before I checked my perimeters.
