How to kill cyanobacteria?
I have relatively new aquarium thats 70 days old with 10 low grade red tiger shrimp (caridina mariae) and 6 otocinclus catfish i just got yesterday. Today i realised i have cyanobacyeria growth on the high driftwood thats brwonish color and a patch of green cyanobacteria on the seachem flourite. I have jun master soil in the substrate and i made a road of seachem flourite just for aestetics and also trying to do carpet with hc cuba. I do use co2 injection and low light at the moment, 50 percent power, blue is very low 25 percent, red is at 90 percent, green at 40 percent and 6 hours a day photoperiod has 30 min ramp up and down and co2 starts 1 hours before lights and closes 1 hour before lights. I have lots of limnophila aromatica at the background i aimed as a jungle look and wanted them to get red so i did lean no3 on the water column but got cyanobacteria instead... now 4 of my shrimps are berried and how can i kill cyanobacteria without harming new otocinclus' and my berried shrimps?
I know i planted hc cuba wrong in the first time please dont judge it its my first aquascaping.
