Do you mean 70 times turnover? Or 70% of the volume turnover? I have 60x turnover in my tank, and I would have a lot more if it wasn't for the LPS that don't like it. Meh, Vortech Shmortech...I like my Tunzes, and I actually don't mind the new Koralias either...they are tiny.

Just creep your dose down a bit lower. You should be able to find a balance between maintaining 0 nitrate and having no fuzz. Essentially, you should be able to quit dosing vodka at some point, but if you overfeed or have poor maintenance habits then you will will have to continue dosing to keep nitrate at 0. Imo any type of carbon dosing should not need to be maintained forever. I see it more as a fix than a maintenance.
