Dapg8gt the reactor is well built and pretty simple setup, I like fact that the effuent is controlled on the intake of the reactor which should prevent clogging, there is also a sediment filter on the intake to keep detritus out. I do have to admit that the reactor should be dead level to make sure that all the air bubbles are vented. I had mine on a wire shelf and had to put a piece of plywood underneath. The unit took four days total to setup, first day plumbing and filling with media, second day running it wide open to let the dust purge from the media, this is even after an initial rinse, then the last two days to find a drip rate which maintained the calcium and ALK....Two days of small adjustments ��. No regrets in regards to the reactor, I would purchase it again.
