Yup, for those of you who don't know, I got a Trigger Systems Cacium reactor. The recirculation intake at the top of the tube cracked. The tube cracked around it. He ended up sawing off the top of the tube and modifying the recirculation plumbing to suck out from the top of the reactor. The thing works like a charm. I'm stoked.
Thanks for the input Chris. I am going to watch this very closely. The effluent pH is a perfect 6.3 with the bubbles popping around 17 a minute and the effluent dripping around 1/second. I'll let you know if I have to make any adjustments.
