Cyano
After my summer vacation i have not had any focus on my planted aquarium, it has been living on its own.
Yesterday i saw a spot of cyano and thought strange i have never had that before, some minutes passed, then i remembered that i have not filled the nutrition auto-dosing containers since we went on our vacation.
The containers was naturally empty, i think i will have to do a water change today and make some more nutrition liquid.
