Does coraline algae scratch acrylic?

[plancton]

I heard somewhere that coraline algae scratches acrylic. I don't know if this is true but would like to know your experiences. I definetely don't want glass tanks. I have a planted tank made out of acrylic, and it's really scratched from not removing sand from the magnet. I sweared I would be extra careful with my future marine tank. But I didn't know about the coraline algae scratching tanks.

Give me some feedback guys.

No it doesnt, but when you try to remove it, you may scratch the acrylic.

[plancton]

Well, that's the thing. How do you remove it then?

[AJP]

You can use a mag-float before it builds up. Or the kent scrapers, but the corraline itself will not scratch the acrylic. If you are careful and don't let it grow it wont be a problem.

Perfect, I will remove it as fast as it appears with my new mag float
