Hello again! I though it would be better to ask then not asking. So, I was wondering how much Airation (bubbles) is too much? I have two HOB's that filter my 60 gallon tank and a Power Head going. So far there's a lot of tiny bubbles floating around. Should I leave the Power Head in? How much is too much? Thanks in advance.

2 HOB's:
Aquaclear 300 gl/hr
Marineland 280 gl/hr

1 Power Head:
Marineland 300 gl/hr

No, you cannot over-airate.
Any surplus of air will just leave the water at the surface.
I use a pond airator with 4 airstones and never had any complaints.
I did put the outlet of my filter a bit deeper so i don't get all the tiny bubbles floating around.
Those bubbles are distracting me when nightlights are on!

Cool! Thanks Noddy for clearing that up for me
