I can't see any bubbles in my tank

[VisibleClownage]

I'm still cycling my tank, and i just noticed that there are completely no bubbles in sight. Does that mean that the tank has low oxygen?
I only run a pump in the aquarium

why would you want bubbles in your tank? Bubbles are unsightly. Bubbles normally comes from the skimmer, if you really want bubbles, you can probably adjust the air intake on your skimmer to produce bubbles. But most people don't want bubbles

Bubbles are not an indicator of oxygen in your aquarium. Good water flow is important for oxygen exchange on the surface of your aquarium.

Oxygen that fish get from the water is dissolved oxygen meaning no bubbles as fish breathe different than we do.
So unless you measure dissolved oxygen content,you will never see it with naked eye

Edit: research surface agitation/skimmers good for oxygen/gas exchange/air stones/equilibrium in nature

Not having bubbles in your display portion does not mean that you have lots oxygenation. The only thing it does mean is you have no bubbles in the display.

Equipment like skimmers and power heads can make bubbles and it's not generally desired to have them seen.

Oxygenation is another side of the card and aren't really correlated. If you don't have anything in your tank that is breaking the surface of the water, agitating the surface, you May have low oxygenation, but it's not because you can't see the bubbles.

This isn't fresh water. I don't even know why they do what they do, but this isn't fresh water.
