sps and alk

ok what will cause the tissue to just melt off an acro faster the high alk or slow alk or just any alk swing? My sps where in a 10.5dkh setting then slowly took the tank down to 9 and lost one acro only one the rest look great but the red tabling acro lost tissue over 3 days completely..bummer the strawberry shortcake is loving the lower 9dkh and growing almost daily wow the most i have ever seen ..any ideas why one species thrives and the other doesn't the deep water acros had some tissue loss on the tips but nothing major they are acclimating well. I am stable now at 9.5 and holding . I want to go total zeovit system and hear that the alk has to be in the 9dkh range fact or fiction?

from my experiance you can run in to trouble with high alk when you are carbon dosing. i would keep your alk between 7 and 8.5. 9 is getting on the high side.

well I was running the tank at 11dkh and brought it down to 10 and ultimatley was taking it down to 8.5-9dkh and thats when things went bad from 10-9dkh all went bad lost one red planet and damaged some of the deep water acro so not sure why this happened did it slowly over 2 weeks because i wanted to go full zeovit . but guess its going to take longer than I thought for them to acclimate to 9dkh unless the acro continue to deteriorate if so then i guess the acro only like the 10.5dkh range ..weird the other acropora are doing great just the deep water and the one red planet that i don't have anymore bummer. oh and the red dragon.there goes some cha ching ..

that is very odd for your sps to react to 9.5 dkh. there are numerous people who run thier tanks at 6.5 dkh with no problem. ora runs there tanks very low on the dkh side and most people would say the perfect balance is around 420cal ppm and 7.5 alk dkh. what test kits are you using?

It's not what he's running his alk at, it's the swinging that's causing trouble. Once a coral has been growing and stabilized at a certain alk and you change it they get stressed and sometimes die.
