Thanks! There's a lot of life coming out if those rocks, I even got a hitchhiker in the form of a sea urchin but haven't seen him today do not sure if it had still survived. I placed a raw shrimp in there yesterday to get the ammonia kicking and my reading tonight was 0.10ppm which is still very low. Some suggest I shouldn't have worried about the shrimp as I would get enough die off source of ammonia from all that live rock I have. They say I should be patient and let nature take its course as I would have created a large bioload, which means massive amounts of if bacteria must grow to deal with the situation and there will be nothing left to feed all that bacteria once the ammonia in the tank is converted and the cycle is underway, which means the bacteria can die off and cause another mini cycle. What are everyone's thoughts about this? Also, should I keep the lights off during cycling or would that kill off all the organisms in my rocks?
