What cyanobacteria is this?

It's irritating kept growing on my acrylic tank.

I believe they are green spot algae, only way to remove them is scrapping them.

Cleaning the glass daily with a good magnet glass cleaner helps in preventing them getting a foothold on your glass and using Phosphate removers to absorbs their good source.

Looking at your pic the second time, it may also be some form of coralines rather than cynobacteria.

Thanks for the replies! Well the problem is, my tank is 25mm thick, the only solution i have now is using scotchbrite kitchen sponge scrub gently to prevent scratches.

I believe they are coralines algae as my P04 is currently undetectable.

What vt_snowman87 mentioned is any credit card or even your ATM card.

I don't think they will scratch.

Of course, you should use those already expired or cancelled card.
