[jimpham1230]

Hi, i need help on vodka dosing, my nitrate is at 0-0.1ppm. When i start dosing vodka, do i need to turn off UV ? Im using api nitrate test kit, how do i know my nitrate level drop to undetectable level? ( like what color? ) thank you!

Nitrate that low doesn’t need Carbon dosing, if anything it’s too low already. Put the money toward better test kits, Salifert, RedSea etc.
