Trying to connect some dots. I have periodically noticed that my alk consumption of .5-.6 dKh/day stalls, and I have to stop dosing while things get back on track. Happens maybe one every few months. No big deal; fixes itself—but have been curious what’s happening.
So this time I discovered the stall when, following a 10% WC, my candy cane frag retracted its polyps by about 80% and has stayed there for about 3 days. Coloration is fine. A BTA and favia also seemed to retract and look mildly—but only briefly—annoyed during day 2. They are now normal but the candy cane is still angry.
Checked the parameters—all normal and stable EXCEPT that my Alk consumption again seems to be stalled. It tested yesterday at 9.7, even though my dosing (kalk, dosed hourly throughout the day) normally keeps it around 8.5-8.7.
I stopped dosing yesterday, and 12 hours or so later it was already down to 9.3, so seemingly back on track.
But the candy cane is still shriveled.
Thoughts on dot connecting or alk stall?
The WC was temp and salinity matched. Same salt.
Normally its polyps are fully-extended during the day, but two days ago following a 10% water change, it went to 80% retracted.
Parameters are
My favia and BTA seemed to stutter briefly with a little retraction the first day, but quickly went back to normal.
I’m relatively new to corals (only 5 so far) so tell me if I’m being too nervous.
