I have a 55 gal
tank with 2 goldfish, 7 cherry Barbs and 1 bristlenose pleco. 2 Marineland 350's for filtration. Substrate is a mixture of Petco "sand" and gravel. I, for the life of me can't understand why I cannot lower the ammonia levels. Ph - 7.0, ammonia stays at 4 ppm
or more, nitrite - 0 ppm
and Nitrates - 80 ppm
(before my water change). I have done daily water changes of at least 30% for three solid weeks. Once an almost 70% water change for no results. I've added more fluval cycle Bacteria than I care to admit. Could my water conditioner be causing the ammonia readings? My tap water has 0 ppm
ammonia. I'm at a loss, can it be this hard? What the ffffff is going on? My fish seem to be acting ok but I do use API ammolock every other day to help neutralize it but that screws my pH up.
