Have you tried RedSea NO3PO4? Ive done Vodka dosing in the past but its such a gradual progress. I now dosed NO3PO4 and its much much quicker. Skimmate can visually verify progress within 2 days. Then again I dont use much per day so cost is for it can justify the positive result yielded. A 500ml bottle lasts me 3 months or so.
