Purchased the new apex el installed it ph probe wouldn’t calibrate. Reset the values tried manual calibration still nothing. Had a tech support call from apex worked for 15 min. 5 more emails with Neptune. To get an rma for the probe. The kicker is I have to pay the shipping back to Neptune. The unit is only a week old. Is it me or is this wrong. When you spend 500 on a controller you shouldn’t have to spend more to get one that works
