alright so i have a 55 gallon tank with 50lbs of live rock. i got the LR last thursday and put in 2 shrimp on last tuesday for a source of ammonia. after the LR came in i added 3 more shrimp and live nitrifying bacteria and a product called biozyme. recently i have been frustrated because i hadnt had any ammonia readings. well today i decided to test for ammonia nitrites and nitrates and i discovered that i have 20ppm of nitrates. does this mean im almost done with my cycle?
