Very interesting info. My nitrates are a bit high (around 20) I tried vodka dosing I got to dosing 8.7ml on day 68. But after 68 days and not seeing any change in my nitrate levels I slowly stopped vodka dosing.
Since I stopped vodka dosing my nitrates have remained at the same level. The only difference I noticed from vodka dosing was my zoos started to shrivel up and die

Since I stopped vodka dosing my zoos are slowly making a come back and are looking better. I would like to try these N/P pellets but I wonder if after a few months of use if it too would have a negative affect on my zoos like the vodka dosing did.
