IMO, a 10% change is pretty conservative. In an aquarium with established vinegar dosing, I think one can raise it much faster. I actually find that in my system, the exact dose is not very important. I've changed it up and down quite rapidly (a doubling or halving, say) and have often not seen any difference. IMO, a week is enough time at a given dose to adjust again if needed.
FWIW, I think many different organisms, all he way up to corals, can take up acetate, so it is not reliant on bacteria to consume it all.
