not trying to get something for free, just want to cross check my results. i have some test kits that are pretty old and before i got out and spend $100+ on test kits id like to cross check someones reputable test kits to my own. mainly looking for calc, alk, phosphates, and nitrates and possibly mag. i was having some issues with nitrates which were driving me crazy with my sps. i have since gotten a new RODI unit and added a ER CS6-2+ nitrates dropped considerably, just based on my kit just dont know exactly where they are. also wondering if anyone has some refractometer calibration fluid. id like to calibrate mine. i can give you a sample of my water or i can go over and test it with you. PM me if you think you can help. Im in davie FL.
