Air Pump
 
I just got my plants in today from aquabid and put them in my tank. It is a 55g Malawi Mbuna tank with about 10 (soon to be 20) juvenile african cichlids. My plant stock is 4 amazon swords and 3 corkscrew vallisneria. I also have an air pump with a flexible bubble wand in the bottom of my tank. I heard that surface disturbances are harmful to plants. My question is now do I have to get rid of my air pump since I have plants? If I do won't my fish run out of oxygen?

I dont use an airpump anymore as its too noisy and i notice the fish staying away from it.
My plants are doing just fine along with the fish.

Ok but my fish seem to like my air pump. They swim up and down with the bubbles. But I am wondering if it is going to harm my plants

I cant see how it could.
If you think about natural rivers and streams full of plants, there's lots of oxygen bubbles created.

The increased water movement and surface water/air ratio caused by airstones and bubble wands cause CO2 (carbon dioxide) to be expelled faster from the water. This is detrimental to plant growth. Surface disturbance should be minimal (=as little as possible) in a tank with live plants. There is not an excess of CO2 in the water naturally, so you do not want to be expediting its removal before the plants can grab it.

As for oxygen for the fish, unless your tank is overstocked this will never be an issue with live plants in the tank.

Alright well I think I may due away with the air pump then. How will I know if there isn't enough oxygen in my water?

Fish will hang at the surface and be listless. But plants produce a lot of oxygen during photosynthesis, far more than the fish, bacteria and plants can use themselves.
