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.

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)
