It is not currently. It happened shortly after my second kid was born so I skipped spending time documenting it. Then the pandemic happened and I had other things on my mind. But really, I just don’t like focusing on negative and didn’t mention on here. Haha.
So quick gist of it, nitrates went from 50ppm to 5ppm in about 4 weeks. A little faster than I wanted but can’t say it wasn’t really effective. Of course there was a bit of loss of color due to such a drastic change of nitrates but color really didn’t fade too terribly in most acros. The ones that got it hardest were yellows and reds.
Fast forward to about 1+ months of use and I see predominately my shortcake, confetti, pink lemonade, and shades of fall losing color and turning basically black. Long term black color turned to STN and death. It was strange to see. Everything else was fine. Talked to a couple buddies running denitrator around the same time and they saw similar things in their shortcakes at least. Decided to kill the denitrator and do water changes for the next couple weeks to flush any potential contaminant out. Corals started to recover and color return. Certain ones are still recovering. I’m pretty sure this isn’t a reaction to the lowered nitrates. I’ve lowered my nitrates like that before without this type of consequence before.
My buddy who killed his denitrator saw the same improvements. So at the end of the day, I don’t know why it happened but I know it started with my denitrator and ended with it as well.
