Some of you already know.
But it's been a rough summer for my tank. I ended up losing some high end and wild pieces in my tank

SSC, most my Wolverine, red planet, my gold mille, pink Floyd, blue matrix, Pearlberry, a few of my clams, pink mille, fire and ice mille, red dragon. Most my purple dragon, bonsai, most my rainbow loom and the most upsetting of it all. My gold Buddha.
Mostly my fault. I had changed too many things at once for me to narrow down the issue in time to save the above pieces. I should've known better.
Long story short. Due to my system being ULNS. My alk spiked to about 8.8 and caused most of the above to melt literally in front of my eyes. If my system wasn't running at such low nutrients, I probably wouldn't have lost those.
I tried to chase that magic number of 2-3ppm no3. Even though my system wants to run at 0 no3 and 0 po4. I've accepted it and will move on.
Lesson learned and lesson to be had here. Only change one thing at a time, and allow a few weeks to see if there are adverse effects first before doing more.
