I tested the water:
ammonia- completely yellow, 0
The temp is good and has been constant. I have plenty of bubbles in there.. there should be enough oxygen?
The only things I could think of, but idk if they would be the cause:
1. I have aquarium salt in the tank right now. Was put in 8 days ago to cure Ich, double the recommended dosage (that's what I was told to do.) I have done a few big water changes, but the tank is still a little over half salt right now.
2. Water level is too low? I leave it like 6 inches below the filter so it makes plenty of bubbles...
3. My plants aren't doing too well, could they be releasing toxins?
That's about all I can think of... I recently just had a tiger barb die. I have 4 platies and 7 tigers in my tank right now. It's a 55 gal.
Any advice/thoughts are appreciated... thank you
