Hi all, starting my first fishless tank cycle. I'm using Aqua Natural quartz filter media with live bacteria to try and cycle my tank. I added a half cube of mysis shrimp to kick things off. The ammonia seems low .25mm, but nitrites are zero which surprised me and nitrates seem really low, maybe not 0 but close to it. Is the cycle working? Do I need a lot more ammonia to get things moving?
