I have been dosing vodka and I am having okay results with it but I started off with lower doses then what they recommend. Vinegar and Mb7 is not clear cut since Mb7 sometimes will not provide the suitable bacteria needed for what you are looking for in the carbon source.
my present dosing:
70ml of vinegar every day, dose via profilux
prodibio : 1amp of digest every 14 days/ 5 amp of tim every 14 days.
speacial blend bacteria -- dose once a month 90ml
this all based on 250 g of water with heavy bioload and a lot of corals..
Jerl I should have mention I'm also using prodibo with vinegar I don't use mb7 I tried it once but ran out continued dosing noticed no difference ! I do believe that prodibo has really helped my tank
Hey matt
based on my exp my dosing comes from corals respond. i start with min dosage, and go up slow and see how my corals respond. also, its bad if you strip nutrients fast - this will lead to STN.
i dose vinegar 10ml per 100g -never had negative results.
