Truth about gas bubbles?

[Klnsheree]

I was looking into getting a seahorse or two for my tank. It's 24 gal. I really like to do my research before I dive head first into something. S I started reading about seahorsesan and their requirements.
What is this about the gas bubble "disease"
My tank gets air bubbles in it from the water flow.
Will that cause them to get the gas bubbles? I am SO confused about it.
Thank you!

no it wont.

IMHO its a bacteria infection/activity. which creates bubbles.

you see tanks with more than 1 male seahorse, and not all get this ... if it was the bubbles, they would all get it.

but iwth that said, the bubbles just dont look good, what is causing it ? try to remove it!
is it coming from the sump ?
power heads too close to water surface ? skimmer output ?
