I have a 65 gal
tank.There are millions of little tiny bubbles in the tank. They are NOT caused by any of the filters in the tank.
The water is clear,except for the bubbles. All water tests are fine.
I have taken a sample to a biology teacher, and he said the water looked very healthy,a few bacteria,but nothing bad. Anyone have any ideas ? I have discus in the tank,2 clown loaches and a bristlenose pleco. I also have 5 baby discus getting ready for this tank,but I do not want to add them until I can figure this out.
