Yes, I've posted a lot since I joined and Im sorry. It's my first tank and I'm learning as I go. I've learned a lot in the last 2 weeks. Anyways, my Black Skirt Tetras were doing better last night. I woke up and they were swimming around together, which made me happy. However, once again the water was a bit cloudy so I added some Accuclear to clear it up (1ml) as suggested for 10 G. Since I added it, my Tetras are acting slow and sluggish and are going back to the surface for air once in awhile. Could it be the Accuclear that is stressing them or something else? Any suggestions?
