For fish that require very high oxygen contents in the water, what sort of oxgenation system is recommended? I have a 110 gallon tank, and was thinking about two Rena 400 Air pumps (rated to 165), but since I am a new to aquariums, I don't know many options available or if something else might be better.

On a side note, I am getting sponge filters as well, and I wanted to know if there were a way to combine sponge filters and airpumps.
sponge filter usually are powered by an air pump.
you can add airstones or a power head the sucks air into its output flow

Definatly use air stones in your Hydro5's but this is only to increase efficiancy. You don't really need much else. VERY VERY little O2 actully gets in the water from the bubbles themselves. What happens is that the gas exchange takes place at the serface of the water....
Basicly...water movement = oxygenation
Less movenent = Less O2
More movement = More O2
The undisputed oxygenation champion of the world is without question a Bio-tower.

AARRRRR... Come on Wolf3101, what do you think you get when you have air under water???? Air/water surface interchange!!!
I keep trying to educate people on this and then someone comes along and regurgitates that statement (that bubbles are ineffective).
Consider the amount of air coming out of an air stone per hour, it's measured in cubic feet. Now consider the surface area of a tank, it's measured in square feet. To start with that's a 4:1 ratio before you even start to measure. A sphere more surface area than a plane (two dimensional flat surface) of the same diameter, obviously, so since surface area isn't changing and air bubble are continually generated ........ do you see where I'm going?
And don't use an air stone if you can help it, get alimewood air diffuser, they create finer and therefore more air bubbles.
Oh, and filter the air supply to the air pump too (otherwise your just injecting air pollutants (dusts sprays) into the tank).
End of rant.

get a aquaclear filter! In my tank the the filter aggitates the surface obviously but it also send tons of little bubbles throughout the tank.
O2 levels change with altitude...that tells me that atmospheric pressure plays a key role in the gas exchange in an aquarium. Water pressure increases with tank depth and the ideal pressure for O2 exchange is at the serface.
The flat plane thoery would be valid were it not for the fact that aquarium water...especially in heavilly filtered tanks with a high turn over rate...is constantly in motion and not static.
Some gas exchange does take place but it's a very small amount...especially in tanks deeper than 24". The water pressure itself restricts the gas exchange.
The ultimate methoud of oxyegenation is STILL a bio-tower. exposing as it does...almost 100% of the aquarium water to the air and allowing the 02 levels to saturate.

Knowing some about the fish you're planning on, I would first suggest that you keep the water temperature around 70 degrees if possible. Cooler water holds more oxygen.
I really don't think you'll have trouble with oxygen content considering the filtration you're planning on. Point the output towards the surface of your tank. The surface agitation will aid in gas exchange and help oxygenate the water.
Scorponok is correct that wet dry filters are good at oxygenating your water. Emperor 400's, if you're still planning on these, work much like a tiny wet dry filter. The water will be pulled out of your tank, agitated, exposed to the air and pumped back into the tank which will aid in oxygenation.
