Why do you all say it's low. Looks like the ICP says 35ppt which is what I measured it using a refractometer that I calibrate weekly.
Would that kill some of my corals if the SG was low? Anything else stick out to you all?
You’re looking at the standard reference. Those are recommended levels.
Your level results are the first column. You have your tank and rodi posted backwards. That’s why you tank value all has undetectable on the first column. That’s good for your rodi though!
you have a few low trace elements as well as some that don’t normally register for me. Vanadium I have to dose, usually undetectable. Copper normally doesn’t register but did for me recently during issues. Same with Tin but yours is much lower than mine was.
bromine and iodide are pretty low too. That is something that is normally depleted in my tank and I have to dose. I wonder if neomarine is just lacking in those elements?
