Best way to supplement kalk?

This is what 12ppm NO3 and 0.08ppm phosphate looks like in my tank.

I've had the same levels of nutrients in my tank as yours for quite some time now and I cant keep a single piece of acro alive. Very frustrating. You have gorgeous corals btw! Nice job.

Two Kessil A380's on a 20g long seems like a TON of light to me.

It's for dat spread and they are running rather low like 30% peak, haven't had any issues till just recently and I've been running them like this for 6 months or so. Also everything, lps and sps have little to know signs of over lighting.....say for the few sps that are fading

i know for me, i have to dose nitrate every other day to keep my levels above zero. i also feed 2 cubes for 3 fishes cut up and spread out throughout the day. if i dont, i get what you are getting with the acro's getting very pale and sometimes my alk raising since nothing is growing. after feeding extra things are chugging along nicely now

Anyone have any input on these two that i mentioned before? The Red sea part A and B combo or the Korallen-Zucht coral system for non zeovit tanks?
