I have two powerheads, 1050 and 750.
Not sure what i'm talking about. But why would water changes not have anything to do with aeration. Unless of course aeration has nothing to do with oxygene level in the water.
My concern is the oxygen in the water. Does the skimmer add oxygen to the water? Do i need something specifically for that? Or am i introducing new oxygen everytime i change the water?
As you can tell, I really know nothing about this. Thanks.
