Elite mini vs. regular diffuser in 75g
I recently purchased a Red Sea Reactor 200 for my 75g's Co2 and was wondering whether or not I should use that or an Elite mini filter to diffuse the Co2 throughout the tank. Right now I have the Red Sea diffuser shooting the bubbles upward into my Koralia pump, but I don't see many bubbles dissolve. Which would be a better choice? I do have this on a DIY setup.
