I have done VSV (vodka sugar vinegar) dosing before and probably wouldnt recommended it. Worked well at the start but I ended up having some problems 8months to a year into it and resulted in some coral morality. I think the best cure for high nitrates is a large scale water change, ie a 50% water change to bring them down to 10. However if you do the large scale water change and they climb up to 20 again, it could mean your overstocked or overfeeding. Either way, I dont think the nitrates are the issue in the situation.
