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.
