Hi All,
I have three large goldfish in a 40 gallon, freshwater aquarium. I’ve had them for about 4 years or so, but am still an amateur by any definition. My tank was cycled for years (based on frequent water testing), so, admittedly, I haven’t tested the water parameters in a bit. I tested last night after struggling to heal scale sores with Melafix on one of them and the ammonia was 8 ppm. *PANIC ENSUED* I immediately did a 50% water change. I also added QuickStart and StressCoat because I was worried my tank stopped cycling and I wanted to treat the tap water I added. I tested the water again this morning and ammonia was 4 ppm. I did another 50% water change and added a normal dose of Seachem Prime this afternoon. The ammonia is still holding at 4 ppm though, so I just added the emergency dose (5x) of Prime. Nitrite and nitrate readings are at 10 ppm. pH is at 6. They haven’t been fed since yesterday morning. Any guidance you have for me is truly appreciated on how to progress forward and reestablish balance in the tank. Thank you so much in advance!
