Two days of vacation and returning I find this misfortune. I made a 50% water change from RODI, changed filters and returned to the old blue light that comes with the tank since I just changed the lamp for one with more white LEDs and just this happened today when leaving work. I will do a test of my parameters since I no longer had time due to work. Today the only thing I know is my salinity which is at 1.026.
