Why do the tips burn?

[Animal-Chin]

I've carbondosed twice and each time when I started my alk was at 9 and my acro tips burned. I find that as soon as you add a carbon source you have to get your alk below 8 or burning happens. I think it has something to do with how carbon and alk react. My nutrients didn't drop so fast that the tips burned, my nitrate was still high when the burning occured. I drop my alk under 8 and everything evens out and the burning stops.

Ya, that's been my experience too, as Alk rises too much higher than 8.5ish the tips burn. This wasn't about what causes it, but more so the mechanism of action.

Far from fact, but interesting to speculate.

I am running out of AF reef salt and going back to IO, AF's dKH is about 8 and IO's is about 10. Should I be concerned with tip burning? How do people with IO and ULNS prevent tip burning, I don't want to work with muratic acid unless I have to.

Could you find coralife salt? Mine is usually around 8 - 8.4 when mixing new water.
