As stated in the title I will hopefully be buying an inline co2 diffusers. Im still torn between the the boyu and the UP. I was just wounding when one of them are fitted what type of filter outlet shall I use : ?
1. Spray bar
2. Lily pipe
3. Eheim fishtail
4. Eheim shepherd crook

Or any others I may have forgotten

Spray bars are probably the most effective in terms of decent all-over circulation, but are generally the ugliest.

Lily pipes do work well, especially if there's plenty of flow. They also look the best in terms of minimal impact on the aquascape, but are fragile and relatively high maintenance if you want to keep them clean.

Fish-tails and crooks work better in smaller tanks.

Thanks George ! Its just I have a spray bar on a Tetra Tec 1200 at the moment and was looking to buy a set of lily pipes but still wanted a good circulation to move the co2 round to all spots in the tank, smart move ? or shall I stick to the spray bar ?
