Does a skimmer remove saltwater?

And now that I've dialed in my refugium with the right amount of flow to lower nitrates to 0. I probably won't do frequent water changes. I'll just be dosing

water changes help maintain ionic balance and replace trace elements

but so does dosing those trace elements, right?

you should test for everything you dose to ensure you are not over or underdosing but the best way to replenish trace elements is with water changes because the elements are in the proper levels and you can't overdose, if you dose trace elements then you will probably get the concentrations too high over time and you can't test for all the trace elements. a 10% monthly water change would suffice.

yeah maybe ill do a small water change.

i've started testing my water with hanna checkers
