all of you have helped out a great deal and I thank all of you. I have another question; my nitrates are somewhere in between 5 and 10 now. I was wondering when it would start to eat up the nitrites/amonia. Those are still pretty strong. I'm about to do another [acronym:b19a9dab52="Partial water change"]PWC[/acronym:b19a9dab52] to help that out right now.
