+1 to that. And the reason you have never seen ammonia or nitrites is simply because the water you used is dosed with so much detoxifiers. And you are WAY WAY overfeeding. The fish don't need to be fed more than a few times a week, first off. Also, I would like you to list all of the corals and other filter feeders you have in the tank. 90% of corals don't need to be feed. I know from your previous posts that you have a frogspawn, but nothing you are feeding it will do much for it. It needs chopped up shrimp or silversides, in fairly larger peices. Mysis or brine just won't do much for it. And even then, you only need to feed it a couple of times a month. Once a week would be pushing it even.
