I mostly used airstones in my pleco breeding tanks. Most of my plecos come from pretty warm water, 84-86F is typical and it can get over 90F at the peak of the dry season. In the wild they live in fairly fast flowing rivers with lots of rapids which serve to keep the warm water well oxygenated. In most of the pleco tank I had air central air running. I was not using all the outlets I could run on my air pump so i was using the spare outlets for airstones to help oxygenate the water via surface agitation.
While the plecos are adapted to thrive in rivers with flow and to handle warm water, they still need oxygen to breath Since the warmer water is the less i it can hold. So it is important to insure adequate oxygen in the water. However, where I use Mattenfilters, I like to have an airstone for both more circulation and aeration.
Like GaryE I use a lot of air driven filters in a number of my tanks. But in my planted community tanks I use Hang on filters for the most part (AquaClears) and canisters. I will run an air powered filter with the ACs as they tend not to restart after a power blink or outage.
