co2 diffusion method suggestion for 4x2x2


So... i have just upgraded my 50gal planted to 120galon planted 4x2x2.
And what type of co2 diffusion is best for my pressurised co2 ?
If im using ceramic glass diffuser, will I be wasting lots of co2 since they would rise to the surface and pop. ?
Inline diffuser? Atomizer?

And around how much will i be saving co2 if i use the best diffusion method compared to the ceramic glass diffuser ? Around 30-40% maybe???
My output pressure is max at 25. So i can't use " UP super atomizer " as it requires 30psi output and/or more. Suggestions please (:

For my 125 gal, I used an inline needle wheel pump installed after the filter. I can't comment on how much CO2 you would save, but this worked great for me and it could be used with any pressure. Just make sure you get a pump nearly equal to the gph output from your filter

I use the ista mix max co2 reactor in my 150 gallon. Its less than $20 and does a good job with co2 diffusion.

are you using any hose clips or cable tie for the istamixmax to prevent leaks ?

No, it came with hose inserts that fit in my cascade 3/4" tube fine. No leaks and sits on the side of my tank.
The crust on the top is from when i disconnected it to clean it cause i have a hair algae infestation. Its not from it leaking. Just didnt clean it up very well.lol

I see. My filter is rated at 1500 L / hour, shoyld i get the M or L size? Since after adding all the media and filter floss, flowrate will surely reduced to below 1000L

It's really personal preference, but you can use either inline or ceramic on that tank. It doesn't matter if technically some of the co2 goes to the surface they'll be plenty being blown around and made available to the plants especially since the bubbles are so small. I've used a Rhinox 5000 ceramic diffuser with a spray bar mounted on the side for years on my 4ft setup. Either way your flow should be fine.

Fluval Diffuser has to be the ugliest, but by far the best diffuser i've used.

it looks like a black donut, but makes the smallest bubbles I can see -- I've never purchased a glass diffuser that made the same type of fine bubbles as this device, and it cost about 1/2 the price (5 bucks for me).
