The 150 gallon rated air pump I purchased and that claims it can run 10 air features barely runs 2 but no more:

Anyone tried one of these:

Links are misleading. Did you buy the Tetra AP150?

 

[fishguy1978]

Yes, I am currently using the Tetra. I have ordered the other to see if it will be able to handle the 4 sponge filters.

 

[Iggy Newcastle]

Well, the reviews don't speak highly on it. Are you using a regulator?

 

[fishguy1978]

4 way gang valve.

The issue is depth ... the greater the depth, the more air pressure the pump has to make to overcome the pressure/weight of the water against the air feature(s)

You may only be able to run two @ an 18" depth but could run 10 @ a 4" depth.
