Is a high Alk level harmful to zoanthids?

[hansnfrans]

I am concerned that an Alk level of 10dKH may be harmful to zoanthids, or that it may stress them a bit. Does anyone know how Alk affects zoanthds? Any good articles on this? Thanks.

10 dKH is fine as long as you keep it stable. You don't want your alk to go up and down. I keep mine at 11dKH.

Acceptable alk levels are 7-11dkh. No worries, mon.
