Not a new tank, and an even older colony. Dozens and dozens of heads, all varieties are looking a little off, but one variety is expelling zoxantilia. There are polyps all over the tank and it's not local. Everything else is doing fine even great. Only change I started having to supplement on top of lime so I'm adding Ca Chloride and baking soda, but I have been doing this since January. Anyone seen large periodic yuma crashes the way Xenia have been known to do?

for the baking soda I assume your still targeting your normal Alk levels? The calcium chloride and sodium bicarbonate themselves most likely wouldn't cause any harm but obviously if the levels were to swing mainly Alk it can have effects that vary from mild bleaching to flat out Rtn.

No flow changes?

Alkalinity issues can do that, chances are you're having some swings from adding baking soda. I'd try adding it in smaller doses throughout the day instead of all at once. Could be something else though, who knows...
