I guess it was way back in Oct 2017, didnt realize. I read the whole thread in one go so didnt keep track.
"My alk was 7 and stable. 95% of the corals are fine, but a few look unhappy still. It’s not a pest. I’ve experienced aefw and nudis and I’m positive it’s neither. One of the corals impacted was a lepto. But I have the same coral in the same water under different lights and it’s fine. Also had a larger colony 5 inches from a frag of the same coral, colony died, frag is growing.
My alk is being consumed at levels I’ve never seen before and recently had to start adding kalk to my ATO as well as two part being dosed in addition to the calcium reactor. I’ve seen growth increase even more with bumping alk up to 8.5"
So you had increased growth but then it went downhill after that basically?
