Lily Pipe Output

I recently installed a set of Lily pipes on my Hi-tech Co2 tank. I cannot decide whether to submerge the entire lily pipe output under water (regular ADA style) or leave mostly emerged with the exception of part of the bottom. Even with using a reactor I am having a lot of gas-off while leaving it mostly out of water. I wanted to increase surface agitation but I am thinking it might be too much. What are the best practices when it comes to positioning the output above/below the water line?

I don't own lily pipes but it was my understanding that lily pipes are suppose to create a whirlpool effect and continuously turn over the surface area of the water. With nonstop surface turnover, you shouldn't need agitation. A slight ripple is enough, no splashes.

Try putting the top of the output a centimeter or two just below the water surface. When it's at the right distance from the surface, physics should take over and create the whirlpool effect. Like I said, don't own Lilly's but that's how I've seen them set up.

Also, if you are experiencing that much gas off, are you sure you don't have a leak somewhere and you're just not injecting as much gas as your gauges/bubble counter are telling you? Could be possible.
Yes, i have used this system for a long time with no leaks. The current agitation is a lot more than with my spray bar
I've always submersed them completely but the water would slightly swirl on top. Why not do it the ADA way? They seem to be pretty successful.
I think both ways will work and be great. Performance will be about the same but I think it would perform better submerged underwater. It will be up to your personal style. free style it and follow your heart. if you like the ripples, let it rip. if you like the natural sound of water splashing like birds attracted to a pond or bird bath, let it splash around. you do you.
