I've now had a second ICP returned indicating low sodium and hence low PSU, latest 29.30PSU!
Last ICP was 30.70, which ended up scrabbling with multiple refractometers and calibration fuilds making me happy my tank was at 35ppt.
Mg and K are at the low end, but Ca is normal. These are were I expect them to be compared to the last ICP at 34.74PSU.
No ill health from the corals but plan plenty of water chances to see if it corrects the issue.
Question is dosing HCl by returning waste water from the Alk monitor causing this issue? I'm no chemist so appreciate any words of wisdom.
Thanks
