I just set up my octopus tank yesterday and installed a bubble wand on the back wall of the tank. The wand creates a wall of bubbles on the entire back of the tank. I really like the look of it but after doing some reading I see that some people don't recommend bubbles in the water column. I was wondering if I should remove the wand. My octopus is not in the tank yet, he is currently residing in one of my other tanks which has a large, circular airstone in it. It is not on the floor of the aquarium, it's just under the water surface so the bubbles aren't floating from the bottom of the tank to the top.
