Best CO2 reactor/diffuser?

I am currently using this diffuser for my new pressurized system. Are there any better options to better dissolve the CO2 into the water?

You'll likely want to look into an inline griggs reactor or an inline cerges reactor.

Both are cheap and easy to build, or you can buy them.

Here's my griggs reactor (black plastic tube on the right hand side)

3" pipe x 20" tall:

Inline diffusers are great and fairly easy to build. However if you just want a ceramic diffuser, the GLA atomizers are my favorite. They create the finest mist I've ever seen a diffuser make and allow you to use less CO2 and still achieve optimum levels of gas in your water.

Folks might laugh, but I've been using a couple of 'cheap' atomic CO2 diffusers from that auction site that I paid $12 a piece for and they're still going strong after 4 years. Can't see paying any more than in all honesty ! They are also on smaller 10/20 Gallon tanks. Any larger I'd go the 'Griggs' style as advised above.

Last one I used was a GLA knock-off from eBay (about $10-12). Worked fine. This was for a 20g. For a larger tank I would look into a reactor.

I used a cerges reactor on my 60g, to be honest I liked it a lot more than the Griggs Im currently running on a smaller tank. Just easier to use and maintain.

Heres the link https://glassboxgardeners.com/thread...2-reactor.346/
