4 LED panels have failed white emitters. Replacement panels for LEDs arrived during the week. Excellent service from Bongy at Inwatter.

Cyanobacteria almost all gone.
Significant bacterial bloom in response to enhanced nitrogen and VV dosing regime ... trying to cut out cyanobacteria.
Also gave alkalinity dosing a boost to maintain 9 - 10dKh.
Sweet, water excellent and things running smooth. Need to swap out panel 3 on LED unit #1
