Just set up my tank and sump two days ago. I have about 50 lbs of pukani rock from brs that I cured for two months in a brute with a heater and powerhead. When I put the rock in the tank I only filled it halfway with water so a good part of the rock was out of water for 24 hrs. I added ammonia to 4 ppm Friday night. Saturday I added a 5 lb piece of live rock from my lfs. I tested the water before adding the live rock and the nitrites were already at .5. This morning I tested and the ammonia was just over 1 ppm and trites were at 2 ppm and trates at ~5. My question is should I do anything? Dose back to 4 ppm, water change or anything else? Sorry for rambling I'm just really excited to finally be setting this up after researching and planning for so long. Thanks
