I have cycled countless freshwater tanks. Does the process work the same? I started the tank and allowed the water to stay in the tank for a week before I started the powerheads. Then checked my perameters. My ammonia was really high. A week later I had nitrites two days later I had another spike in ammonia. This repeated over the next week. Now I have 0 ammonia, my nitrites seem to be on the downhill slope and my nitrates are slowly rising. I added all of the rock today so I expecting another ammonia spike in the next week. After I get through this next spike and my nitrites hit 0 is it safe to add a damsel or two? Or possibly a clown or two? Just to start with. I know I want clowns and a damsel or two. What are the best clowns to get?
