Shades are on the Radions.
Haven't posted parameters in a minute. Here's from last week. Phosphate wars continue. Everything else is pretty stable:
Friday, Sep 4, 2026
● Dosing 10.0 ml/day AFR starting 7/28/2026. New batch AFR starts 7/3/2026.
● Tests are post-today's AFR dosing.
● Phosphate, nitrate tested before a.m. feeding.
○ Ca: 470 ppm (+10/14d)
(target: 400-450 ppm)
per Salifert titration
○ Alk: 9.6 dKH (nc/14d)
(target: 8-12 dkH)
per Salifert titration
○ Mg: 1,380 ppm (+60/14d)
(target: 1,250-1,400 ppm)
per Salifert titration
* Stay with 10.0 ml/d AFR.

per Hanna ULR Checker
* Re-test phosphate on 9/8/2026.
Had some cyano or red algae on a rock.
My Pencil Urchin found this patch last night and seems to be taking care of it without further intervention on my part.
Here is my AWC performance stability over August. I think that piece is good to go for an extended vacation:
I just need a tiny UPS to prevent time reset when the power flickers. It only needs to last a few seconds without grid power before the whole-house generator kicks in.
