Spraybar holes

I am getting ready to drill my new spraybar and was wondering where you have drilled yours and if you are happy with the results? If not what changes would you make?
Mine is a couple of inches from the top of the tank full length.

Mine are all drilled in a straight line down the length of the spraybar. This allows me to rotate it to the position I want.

I was thinking about having them point in different directions but maybe that is not necessary.

I initially had a spraybar along the back of the tank pointing forward just below the surface to reduce CO2 off gassing, but found I got a buildup on the water surface. i just run (2) 90* return elbows now. Just enough agitation to keep the buildup down.

I ran a 36" on 48" for years and found that a straight line is better than staggered. I no longer use my bars though, I too use 90's.

If you have co2 diffused through your canister or inline with a diffuser I would have a few pointing up to help optimize oxygen getting into the water as well. I have over the past year or so found that I can run much higher co2 levels (super yellow Drop Checker with 4dkH solution) with no fish stress at all when there is a decent amount of surface agitation.

I also use a 90 degree in the left rear corner, aimed straight at the front glass. This creates just enough turbulence to eliminate surface scum buildup and adds O2. I only need to add about 1.3 bps co2 for a slightly yellow drop checker. I use an in inline diffuser on the output of my canister filter. The aquarium is a 46 gallon bow front.
