Which Korallen Zucht products work for you?

[Reefinometry]

Im thinking of trying this brand out to help enhance coloration and polyp extension on my sps.
With some many korallen zucht products, I dont even know where to start or which ones people stand by.

Lets hear which are some of the best products they make that you like.

Thanks!

I dose coral vitalizer and sponge power (I keep sponges).

I haven’t paid attention to before and after tbh, once I finish the bottle I’ll likely stop as my tank is high in nutrients anyway.
