mine's not changing colors at all on my nitrites and i need to be checking it to see if my tank is cycling. i bought live rock that was already cured and i have 15lbs of crushed coral and 3lbs of argonite live sand that came out of a tank that was already cycled. and i have 24 blue legged hermits and 1 blue yellow tail damsel and my water is clear no diatoms or anything so i dont know if it has already cycled or hasnt' yet or what. the tank has been set up for a week and half. do any of ya'll have an idea of what i need to do or if it my already be cycled?
