Rapidly Declining Xenia

Instant Ocean salt. Sand bed is 3 inches deep

I use IO salt and after aerating and mixing with a powerhead for a couple of days the alk of freshly mixed IO saltwater measures about 10-11.

I have trouble maintaining the alk in my tank between 8-9 and I add about 2 teaspoons of Seachem Reef Builder (carbonate alkalinity) daily.

I'm just trying to figure out what is causing your alk to be so high since you are not adding any alk supplements.

I suppose I'll have to check my tap water. I use a DI unit for my new water so I always assume that it gets everything out.

How is the xenia doing now?

Not much better, I'm afraid. But not deat yet.I got the two separated stalks off the bottom and rubberbanded them to a small rock. They still extend each day, so they are still living. I'm crossing my fingers.
