I'm having a problem with my ph probe on my reef keeper light .I calibrated it when I firdt hot it and It was reading true.in the passed 2 weeks it'd been all over the place I've calibrated it a dozen times and it seams like its working fine after the calibration then within the next day its all over the place with very low reading 6.2 6.8 .my corals look fine so I Def know my ph isn't really 6.2 .how long does calibration fluid they give u with the rlk last I'm thinking maybe my cal fluid ain't good .also is thst normal to recalibrste a ph probe after only 3 months use
