Algae ID

[Red Sea reefer]

Hello everybody so I have green algae growing on the glass it's really hard to remove , All my parameter are good po4 and no3 are zero I do 20% water change every ten day I run a GFO and change it every two week for lighting I use LEDs full spectrum . Below are some pic and I really need help with that
The tanks is 150 gallon , the attached pic is for the front of my tank

It's probably coralline algae, which comes in different colors. I've got a plastic razor blade to scrape the glass with.

Looks like typical green algae on glass.

Needs to be scraped.

I have similar to that on my glass and I've got to use the scrapper and the scrubbing pad to get it off. Sure glad I've got a glass tank.

So is it a coralline for sure ?? Or it's might be a green algae
How often you clean your glass I am really tired of doing this

I have the same thing and I am pretty sure it is coraline, I also have smaller amounts of pick, purple and red coraline elsewhere in the tank.

Green film algae...common to all tanks with strong lighting, I use my mag float every other day to remove this from my reef, definitely not coraline algae.

Green film algae is easy to get off the glass, coralline is not. Yes yours is coralline algae. Once you get the coralline off of the front glass or the sides too for that matter it is easy to keep up. I run my glass cleaner once or twice a week and it takes just a couple of minutes after you get the coralline off. I also have a powerhead pointing at the front glass which helps keep algae away from forming on most it.

See how the coralline algae grows in circular formation....yours is NOT coralline algae, green film algae if left un-scraped becomes harder to remove, this is the case for you, I can see it plain as day, just use more elbow grease, it will come off & will be easier to keep off if you do it every other day.
