I like the zeo theory & results as well. But the full system with the reactor does not fit in my current tank or with my lifestyle either. I've gotten fairly good results by dosing some of their products & doing 10% weekly water changes. As well providing as absolutely stable as an environment for the inhabitants as possible. I dose vodka & have for 6-7 months & in the last couple of months have started to use zeo's start3 in combination with the vodka on alternating days & slightly different amounts. based on what my tank has started to show. I try to stay as consistent with alternating supplements & dosing what on different days, but know that with out keeping record on paper, I personaly make some mistakes or forget some stuff. Just dose less than the bottle says & pay attention to the results. Look closely. Here is a link for vodka dosing
