Here's a couple of the rear chambers. Far right - (Chamber 1) has probes for temp and pH, in & out for the HOB-1, flows over the director into Chamber 2 (Middle) where I have the media rack, ball of weeds (chaeto) and then finally into chamber 3 (far left) where the dosing happens, the ATO and return pumps.
Again, older pics, sorry 'bout that.
