The 3rd tube I brought to the front for light spread.
I'm supplying Co2 through an fx5 where up until now I have had one of the out let's pointing to the surface.
But due to the extra light now I've had to point both outlets down now (for the Co2 to get in the water due to the Co2 being in more demand than ever.
So I figured I would get some o2 (maybe more also) via a stone.
