What type of Algae?

[Antunes]

Started occurring after I installed co2. I lowered lighting from 12-10 hrs. It’s growing on plants too. From what I read it could be blue green algae (hopefully not). I don’t have a phosphate checker but nitrate is 20-40 ppm ( hard to tell on strips but definitely in that ballpark). It’s my first planted tank and has been up for a month. I never experienced green algae before so thank in advance.

Hello Ant...

Algae of any kind will become a problem, if the plants and fish aren't using all the nutrients. Nitrates and phosphate are the reason. If you can reduce these, the algae won't have a food source and won't grow as fast. You can also use house plants to reduce the nutrients in the water. I use Chinese evergreen. The roots are immersed in the water and will remove all forms of nitrogen from the tank water. I have no visible algae in my tanks that have the house plants growing in them.
