I setup the tank a week ago now, threw in the nice fresh shrimp and let the tank sit, so yesterday I tested my ammonia levels and they were at about 0.5 (using the API liquid test kit) and so I let it rest and then today just for practice I did the test again and tested all the rest as well.
my ammonia is down to 0 and my nitrites and nitrates are also at 0. Did the cycle have a mini spike and now nothing?
but at the same time my white sand and LR
have turned brown, the LR
went from going white, to slight purple then brown and the sand is turning brown all over the place.
I found I have 4 or 5 small hermit crabs as hitchhikers and they seem to be doing ok.
Also the Media in my filter I have is from an established tank, the tank setup for over a year so any ideas if I maybe stalled the cycle out or is this normal?
