James Croney Posted November 24, 2020 Share Posted November 24, 2020 Ive bought myself a 3-something gallon hexagon tank for my desk. I've got myself a nano usb airpump and neverclog airstone, and some other things from somewhere online to help complete the tank. Id like to ask whether an airstone's vertical placement in the tank makes much of a difference for dissolved oxygen. I understand that some lesser amount of oxygen will not dissolve as air bubbles will travel less distance if the airstone is near the surface. My feeling is that "I want all the oxygens I can get omnomnom" but my curiosity has me considering how much I can get away with. If the difference is minor, I might be able to get away with a 'low flow' tank. This most likely would be terrible as the water volume grows, but for a 3 gallon even 2 inches under the surface is a large percent. -- Besides curiosity, i have an accidentally rimless tank that i would love to grow duckweed as my tank lid. The guppies would love that too. The airstone being near the surface doesn't transfer as much force to disturb the water outwards. If the water surface moves too much duckweed gets unhappy. The tank is lightly planted with some guppy grass and some clay pellet substrate. Also has a wondershell in there. Thanks for reading. 🙂 1 Link to comment Share on other sites More sharing options...
