I’m having an issue with my trident. Has worked great for the past couple months. I replaced reagents two days ago and after I calibrated. Worked fine. Then today I get a “bad alk range” blinking. I immediately test with Hanna and get 8.7 so should be within range for trident. I recalibrate and after I’m getting the same thing.

any thoughts on how to fix issue?

my calcium is also higher than normal at 477. I don’t currently dos calcium and just started dosing alk to keep it up.
Thanks.

1. Verify the Alk reagent tube is not pinched.
2. Check if the metal tube inside the Alk reagent bottle has detached.
3. If that's not it, remove the reagent bottles and pull out the tray so you can look inside the Trident to see if the reagent tube is still connected to the internal valve.

This happened to me a few months ago and after a bit of troubleshooting I discovered that the sample tube had gotten clogged so it wasn‘t able to take in water from the tank to test. I disconnected the sample tube and blew it out which resolved the issue.

Ok. Will give that a try tomorrow. How did you blow it out?

The most effective way to blow it out is to connect the sample tube to a syringe (use the little fitting that connects the sample line to the short pigtail on the back of the trident) and force water through it.
