Monitor your water parameters. Ammonia and nitrites will go up and eventually go down to zero. Nitrates will be high at that point. You want those zeros at the end. Shrimp goes out at the end...do a partial water change to lower the nitrates and add fish. I think a fish or two every three to four weeks works well and allows the bacterial colonies to increase with the increased waste they are working on. The entire journey should take about 4-6 weeks.
