True, and another thing are the plants. I'm assuming this is the tank with the sword and more plants to come...forget bubbles. They drive off the CO2 that the plants need. Water movement in a planted aquarium should be minimal, particularly with respect to surface agitation where the gas exchanges occur (oxygen, CO2, nitrogen). B.
