So I've read that I should use a gravel vacuum and that I shouldn't. My 5 week old tank has high nitrite and high ammonia 2.0 ppm for both (after two water changes today!) From reading it seems that not having used a gravel vacuum yet could be the problem? But I've also read not to use them if you don't have an under gravel filter (I don't). I currently have two ocellaris clowns and a yellow tailed blue damsel. Please advise!
