Hagen Ladder vs DIY Chopstick Diffusion Method

I have a 55 gallon aquarium that i recently started up, and this is my first dedicated attempt at keeping one. I just hooked up a pressurized CO2 system (2.5lb cylinder with a Milwaukee 957 regulator) and I have a question about the best method of diffusion between my two available options.

I have a Hagen ladder left over from my previously failed DIY CO2 attempt. In the picture below, you can also see i have an airline with a chopstick bit shoved in it.

I currently have the CO2 running through the Hagen ladder but was wondering if I should switch over to the chopstick airline and just run it directly underneath the canister filter output to aid in dispersion.

I plan on getting either a glass diffuser or an inline diffuser sometime in the near future, but what do you guys think would be the best option in the meantime?

Neither is adequate, IMHO, for a tank that large. Could you position a powerhead over the hagen ladder or the chopstick to chop up the bubbles as they come out of the top of the ladder/'diffuser'? That would be best. If I recall correctly (it's been awhile since I used one), the hagen ladder won't be able to take as high of a bubble count as you'll need.

in the meantime i would use a airstone or chopstick and the intake of my filter as previously stated neither will get the lvls to where u need them the ladder is diy an even then you still lose 30%+. you could make a 20oz bottle rigged upto the outtake and have the bubbles collect there and that with the flow would diffuse better than both the chop stick or ladder imo, then get the eye sore out of your tank when ur diffuser arrives

I wish there were a ranking of the effectiveness of certain diffuser methods to know how much better one is than the other

Thank you guys for the help I think I will switch over to the chopstick for the time being

You could just stick the end of your CO2 line into the intake of your canister filter. That would be better than either of the methods proposed.

I did consider that method but I've read online that it would do damage to the canisters impeller. Have any of yall had experience with that?

those little ladders can work pretty good on small tanks, i had a 3 gal eclipse with one in it, and the bubbles would shrink down to nothing by the time it reached the end of the ladder. on a 55, like mentioned previous neither is adequate. my vote would be for an inline rex grigg style reactor. until then, you can ghetto-style it by running the co2 into your canister intake.
