I don't have nitrites but a little ammonia.. It's strange because i use cycled water.. same for filter.. The tank don't smell ammonia.. But test kit detect ammonia... So i've test cycled water, and i dont have ammonia..
I dont know why i have ammonia on a naked tank..
I ve bought 2 L46 but one is dead this week.. The other is thin.. He don't eat so much. We have try to give him differents food.. but its hard.. He eat a little artemia and Brine Shrimp.. Actually he is on a hospital tank with two ground pots, an air pump and a filter.
