I'm new. I've got a 30 gallon tank that I set up with an Eheim 2215 filter. I bought some SeaChem Stability and used it according to the directions for a week. Based on another post I've made I discovered I had to add something for "food" which I had not done. At this point I planted my tank out and added one pinch of flake food. Today, about a week later, I tested my water and found my stats to be Ammonia 0, Nitrites 0, Nitrates 5.0 ppm. That seemed good until I tested my tap water which had the exact same measurements. Now I haven't done a water change since my plants went in so I don't know what those measurements mean exactly. I really want to make sure my tank is fully cycled before introducing fish. How can I tell if my tank is fully cycled other than the tests I've already performed? I've got some Fritz Pro Aquatics Ammonium Chloride (NH4CI) but I've not used it yet as I'm not sure of the process or if it will actually reveal the state of my tank. There are instructions on the package detailing the amount to use to bring the water to 3-4 ppm. So what's next? Add some and add some more Stability and check every day? Any help or insight would be most appreciated. Thank you!
