Default Potassium

So I have been dosing the Brightwell line for a bit now and am still wondering if it is doing anything. for my SPS. So I bought some potassium supplement and a test kit. The one that JL had in stock Korallen-Zucht. Anyone use that one? A bit finicky to use but I think I got the hang of it. (Best viewed in natural light)
I am running at about 250 parts as far as I can tell.
So I added the max per day amount for two days and I had some algae on my glass for each of those days. I never have algae on the glass as I have no fish right now.
Tested today and am still at 250 so wondering what other reefers experience is with that. (Added more but only half the max amount)

Why are you dosing and testing for Potassium?

Potassium aids in the growth and colorization in SPS.

Do water changes not keep the levels high enough?

You are correct it should be in 350-380 range

Water changes usually don't account for Pottassium, not enough to keep parameters where they should be.
