I've maintained alk around 7-8dKH over the past year. Recently, I switched to a bubble magus dosing pump and from Seachem ReefFusion 1&2 to ESV 2-part. In the process, I've made a few mistakes and now my alk is around 9.5. I think because of this, I've managed to stress out a few of my acros. They've developed white tips and are also sliming from the tips. This is not new growth because these are established mini-colonies grown from frags. Not sure the higher alk is the problem, but I didn't have this problem before the move to 9.5. It's been about a week around 9dKH and the acros aren't sliming as much, but I'd like to lower it back to 8. I don't want to add to the stress with a rapid drop, but I also don't want to continue to stress them out while I let it fall over a week or so. How quickly should I let it drop back down? I estimate that I'd drop just over 1dKH/day if I didn't dose. Any insight would be greatly appreciated. Thanks in advance!

water changes and wait or http://www.reefcentral.com/forums/showthread.php?s=&threadid=1530419
Thanks for the reply, but will skip the acid approach and water changes won't help because the salt mixes to 9.5dKH. So, considering I believe the acros are already stressed from the rise, should I not dose for 1 day and let it fall 1dKH throughout the day, or should I dose less than normal and let it fall .x dKH over a week or so?

Just adjust the dosing pump, I checked mine for the first time in months and after 14 drops I realized the problem and cut the dosing schedule. Just make changes slowly and you'll be fine.
