Do these airstones make any difference?
I am trying to increase the aeration in my biocube 14. I have added 2 airstones to the back. 1 in chamber 1 and 1 in chamber 2. I was just wondering if the aristones in the back help with the aeration any or if it is just a waste of time. I am not really sure on how much circulation an airstone really provides. I also added a small powerhead in the tank to circulate more water around.
