Hey guys. I’m no longer using these guys. The phosphate meter works great and comes with some extra packets to test. The refractometer reads 1.028 when it’s 1.026/35ppt. I know you can recalibrate these guys, but too lazy to figure that out. Open to nice sps or zoa trades. Local only for trades. Will also take a 100 for both shipped. Feel free to send a text
