LOL Sorry epic, I'm the opposite. I have 2 inline reactors on my 125, and got rid of my diffusers because I found the bubbles unsightly.I have used both diffusers and reactors and I personally like to see the stream of bubbles from a diffuser...I have a manifold to split the CO2 into two lines. One is going into a diffuser and one is going into a reactor.
You can do a DIY reactor for ~$15-$20 in parts...and I have a FS thread in the Swap n Shop forum. Or you can PM me if you're interested in the diffuser. Rhinox 2000 = $20 shipped, Rhinox 5000 = $22 shipped...brand new.
