Ok, so I bought a maxijet 1200LPH powerhead with airtube connected above the surface. I have it pointing at surface with the FX5 outlet both breaking up the water. The bubbles are great, seems to help airate the water and break the surface layer of particles that sit on the water which I mentioned in another post (probably decaying food or something but almost all tanks get it and it decreases O2 exchange on the surface).

My question - can you have too many bubbles> is it a danger to fish? They start off as quite big bubbles coming out the powerhead which break up into thousands of little ones. Is this a problem, or ok to leave it. (I know you can turn down the bubble volume)
 
The only issue I see is the air getting into the intake of the FX5, reducing functionality. Apart from that there is no problem.
 
Actually, there is a condition in which the water can be over-oxygenated, which in turn kills the fish.

Someone with a more scientific background will elaborate further.
 
if you are feeding straight oxygen into the tank then yes.. i forget the fancy term but using 100% oxygen does something which messes up something with the co2 levels and the way it does whatever in water and some other stuff that i cant think of and will end up killing your fish.... but again... this is only when using straight oxygen..

when using bubblers and air stones and just pumping a whole lot of air into the tank... no... no real risk of any harm to the fish... ... that said... you can make them less than comfortable and possiably "burn" their gills from the constant contact with "air"... unless the bottom of the tank is nothing but airstones thats no really an issue....
 
What size tank?
 
I use a pondsize airpump, and made it soundproof and got 4 airstones to it,my water is extremely airated, and my fish do very good.
plus it heats my tank better as a got no heater on my tank!
