Ammonia

[Trigger Man]

The link given already is good help. Yes Prime will help lower ammonia, and you can use more then one dose if needed (I think it says that you can use up to 5 times the dose). The best way to get rid of rising ammonia is through water changes and good filtration. As a note when feeding frozen foods, you must remove the non eaten portion, so that it does not decay and cause ammonia spikes (may be over feeding). If you are having ammonia problems I am assuming that your tank is a newer setup and is still cycling through. You should also check to see if anything in your tank had died and is now decaying.
