Hi, I've purchased brand new apex end of last year kept it in the box since as I was waiting for a new tank. So last night I've set everything up and I'm having hard time calibrating the salinity probe, even the first try when the probe was completely dry still failed, did tap the probe to get all the air out etc after multiple fails last night I left it to dry overnight. This morning same story it will settle the reading but next to "acceptable range" still have the red triangle. Any ideas how to get this sorted I'll order some new sachets for calibration is there anything else? I've seen people doing manual calibration but not sure how that works as I'm new to Apex. Any help is much appreciated thanks
