What you have going on in the tank is not enough bacteria and/or macroalgae to process the ammonia being produced by some factor(s). In earlier posts, you say you have just moved the contents of a cycled tank to a new one. Perhaps stuff in your sandbed died and is contributing to the ammonia. Perhaps your LR was out of water too long during the changeover and bacteria and other stuff on the rock began to die. Additional food for your new fish might also be playing a part here, too.
Did you add any new rock that was not cured when you switched tanks? Is there leftover food floating around after feeding time? If you can find a cause of the ammonia, you might be able to remedy the situation.
I'm not an expert on skimming and don't know if having a skimmer running would significantly impact your ammonia problem. Hopefully someone with experience in this area will offer an opinion.
