Green hard algae

i get this really hard to remove algae that grows on my front glass it is green and hard like rock it covers the galss sometimes somone has tried to remove it before by using a pice of steal wool it did remove it but the glass is all messed up so i need to replace it pretty soon but i know it is going to grow again so how do i remove it from the front glass i am not worried about it growing on the other glass it is just to remove it from the front glass

 

just remve it with a blade!

 

i found that to work in the past anyone els have a better idea

 

best bet is a glass scraper they have a stanley blade in them. it is manual but it works the best

 

i feel they work fine if you get a good one! i remove corraline so i dont think the green algaes will be any problem at all

 

thanks people this seems the best method as everyone is doing it thanks for your support

 

cool man

 

intresting methord thanks

 

Tip I got from Psycho was to use a paint scraper. Really cheap and can get them in wide options. Also heavy duty so are a lot better than those plastic thigns that take a minora blade.

I use one now all the time for coralline and it works very well, much better than scraping each coralline spot with a credit card.

 

I did that. It works but damn, it's still a lot of PT.
