I was hoping someone could help me. I set a 180g reef tank up seven months ago. I am not running my skimmer or any form of waste removal, just moving water with sump. It still has not cycled. The ammonia is reading .25, 0 nitrites and 0 nitrates and has for about six months. I have added many different live bacteria to it. I have had fish in it for several months hoping it would jump start the cycling process. I have even added a couple of dead shrimp in the sump hoping to increase the ammonia. The levels stayed at .25 and the shrimp have rotted. Has anyone have any advice. Thank you and God Bless.
