This is more what I was getting at before. whether you are intentionally ULNS or not, high alk with low nutrients can cause tip burn in acros and I have found it to cause birdsnests to die from the inside out. So if you're doing a good job at keeping nutreints low, well then alk might be an instigator of this.
