I know this is not the appropriate location to put this post. If it gets moved, I won't throw a hissy. :tounge_out: The thing is, at one time, I was interested in purchasing a certain system from one of our sponsors, had a couple of questions, but never got a response. Well, after talking to a couple of members, I determined that the system would not fit my particular application. Anyways, long story short, now I am looking for an oxygen infusor to place in the line for the recirculation pump. I have seen such a critter, but not sure if or where just that component can be purchased. If someone could lead me in the right direction, it would be Waaaayyyy cool.
