Ok so I have a 10g and the cycle just finished on Sunday and so I did a water change added 5 hermit crabs and a turbo snail something small I guess so now that I'm waiting I did a quick check on my parameters and I notices my nitrites is up like .25ppn it wasn't up when I did a water change am I doing something wrong and also .y water is a little smelly I leave the light on like 8 hours a day so I'm not sure what I'm doing wrong and my hermit crab arnt really moving a lot is that normal??? Thanks guys
