Hey everyone. I've been cycling my 72 gallon tank for 8 weeks now. I ghost fed for a few weeks, then stopped. I have ammonia, nitrites, and nitrates. Used both red sea and api test kits. I did do a 15% water change a little over a week ago. My nitrates were over 50. Question is my ammonia is still .8/1.2 nitrites holding steady at .2 nitrates are down to 20/50 since the water change. Ive been adding microbacteria daily. I went through the sand bed during the water change thinking that there is still decomposing food down there creating this onslaught of ammonia. I want to add fish but i cant due to this. Is there any advice out there or should i just continue waiting and adding bacteria till i hit 0 on ammonia and nitrites? I have been running my skimmer and changing my filter sock every 3 days. Also i have 1 hammer coral and one zoa that ate thriving for the last 3 weeks in there.
