I have seen planted tanks in which co2 bubbles go from right to left like a river current. What kind of filters do this?
I have a whisper 20i and 10i in my tank which all they seem to do is make swirling vortexes, idk if you can see them in that picture but they are in back on left and right. Maybe if I put the filters on the sides with one closer to the front and one closer to the back they might make more current instead of a vortex? Any and all insight welcome and the lower the budget the better DIY works too.. Thanks
