I just recently bought a product called ammo lock from the lfs. I am currently trying to reduce the amount of ammonia in my tank. After cycling the tank now for about 3 weeks i did a water test, it showed i just had an ammonia spike. I didnt think it be anything too big to fuss about b/c i just did a 25% water change two days ago. Plus the Bacter Vital i used told me that the test results would show more ammonia than what is really there. Today i was observing the fish, i noticed they were all stressed to the max. i tried another water change, but the same results occured. SO taking my fish into consideration i rushed to the store awhile ago and purchased this product. I took my filter out b/c the direstions told me too since i have a carbon filter. How long does iot stay out? when can i put it back in?
