I recently upgraded my glass 46G bow front tank to a 125 acrylic.

I was so easy to clean my glass tank.

Now, a green film, algae like is covering the tank. I tried to clean it
but it's really stuck on the acrylic, I'm afraid to scratch the tank.

Any easy way to have a clean display?

They make scrubbers/scrappers specific to acrylic. Did you try these?
