I have a 12 gallon Nano cube and I've had the tank for only 1 week now with water and plants in it. I'm adding nutrients as needed for the plants and last night noticed some reen algae in the substrate and a little on the glass. What should i do to treat this as I know their isn't enough bacteria in the tank yet to fight this stuff off? Should i not put the light on as long or is there an additive to treat with? please advise!
