As far as the plants are concerned, the water sprite in my 250-litre has gone absolutely mental and I'm going to have to pull some or all of it out. The other plants are holding their own, nothing has died on me, so I'm not concerned about having the airpump in there. I may have done the "wrong" thing, but I'm comfortable with it. The fish seem ok, my plants are alive, the water parameters are good, so.... shrug.
There really is no right or wrong. The quite delicate natural balance in a planted tank has many factors and each aquarium is somewhat different. As long as you achieve a relative balance between light and nutrients, it will be fine. All of the "suggestions" we toss around are intended to help guide those basically new to planted tanks; so many have them fail, and give up, so it makes sense to recommend things that are less likely to contribute to failure. As we each progress with experience and success we learn how to fine tune.
As for fish suffocating, this is highly unlikely unless the tank is overstocked, something gets in the water, the bacteria die off in the substrate...basically some disaster has to occur. There is more oxygen and CO2 in a healthy tank than you would imagine.
