I sure do like my ca reactor. I have the mrc nano. It is a dual chambered reactor (one for reactions and one for buffering). I picked mine up from SEA. The very first day I got it, I managed to over tighten the micro ball valve and broke it. I was pissed! I live about an hour from the shop, so it was not convenient to turn around and come right back. I called Jeremy, and with help the from my loving wife(she was in that area) , he hooked me up with a new piece, and I had it running that day! Excellent equipment from a great shop.
