Poll: Do you measure/control potassium in your reef?

[UWC]

We test potassium weekly on our tanks via Salifert and adjust to 420ppm

Well i received the Salifert test and to my surprise i got 400ppm. Never tested it before with mi 15 gallon bi-weekly water change with Reef Crystal.

Now the question is should i bump it up or leave it as NSW at 400ppm?

Thanks for the advise.

Hard to test
Use Red Sea test kit

The salifert is much better
