So last weekend I started my new 28g nanocube with 30lbs of live rock and 20lb sand. I checked the water throughout the week and everything seemed to to sit at exactly perfect. Over the weekend I noticed a small dip in ph and ca since my rock has a lot of growth and even some coral frags already growing on it. I supplemented it with ca and it seems to be on its way back to normal but I still haven't been able to see any change in ammonia, nitrite, or nitrate yet. I assumed this was since the rock was precured and didn't have the die off to really create bacterial food to spike anything. I added some raw shrimp to the tank just to give it some bio material to break down in an attempt to get things started and after 2 days still don't see any changes to parameters. I know a lot of people use a cheap fish to produce waste to cycle the tank but I would prefer not to go this option for a variety of reasons. Is the build up time from adding waste to seeing ammonia that long or is something else going on? I understand cycling is a longer process but it doesn't seem that anything has even started yet within the tank.
