I've switched salt to Meersalz Pro and have been using GFO to bring phosphate down and Instant Ocean nitrate reduced to bring nitrates down. Both are trending downward but I'm trying to make slower changes instead of big changes. I've heard of vodka dosing but don't know too much about that. How do you vodka dose?For your eyes, get Hanna Checkers. I find them to be +/- 3% of ICP tests.
For zoas, yeah too much no3 irritating them. I dose vodka and maintain no3 at 10. You'll see a world of difference.
