Randy. It doesnt make sense to me why people are adding .5ml of vodka per week regardless of the size of tank. Clearly in my case where i have 1300gallons of system water , this process wont get me to find my correct dose to keep nitrates dn until way too long. How can it make sense that the guy who has a 100 gallon tank and has less than one tenth of my volume add the same amount of increase as me ??? Can i go up faster. ???? Like a ml increase per week or more. ??????
