Alright I decided to try the ammo lock to see if it really helps. My tank is in a mini cycle. It has been getting better but very slowly I'm hoping this works like the package claims it should. 3/25/12 after a 50% water change my water tested: Ammonia 0.5ppm Nitrate 40ppm Nitrite 0ppm I dosed ammolock as the bottle directed and it says dose it every 2 days until ammonia is no longer detected. It says if it lasts more than 7 days to clean the tank, service your filter and reduce feeding. 3/26/12 (no water change) my water tested: Ammonia 0.25ppm Nitrate 30ppm Nitrite 0ppm I will continue to update this post as I continue to go though my cycle. UPDATE: 3/27/12 -- Tested water then dosed tank again with amount directed on bottle. Ammonia: 0.25ppm Nitrate 30ppm Nitrite 0ppm No change, hoping to see change again now that I dosed the tank again.
