I'm wondering why consistent feeding doesn't have the same impact as vodka dosing? In each case you are adding carbon, and conditioning beneficial bacteria populations to grow. Is it because the vodka dosing doesn't result in adding even more nitrate and phosphate, and feeding does? Over time my small Red Sea Reefer 170 has begun to accumulate phosphate and nitrate and I'm trying to figure out what is the most efficient way to address the problem.
