best algae removal for an acrylic tank?

[jimi thing]

What's the best and safest way to remove dried algae from an acrylic tank?

My sister-in-law has an acrylic 180 that she needs help cleaning. The thing has some pretty thick algae all over it and it's been sitting dry for about a week.

I tried some white vinegar and water and scrubbed with an acrylic safe aquarium scrubber and it didn't really do much good.

Anyone have any tips that might make this job a lot easier?

Try novus scratch remover with a polishing wheel. It worked for me.

If the tank is full, Magic Eraser works well. If empty, a mixture of water and vinegar at 50:50

Do you mean Magic Eraser the Mr. Clean sponge product? Does it work on coralline?

I read a thread about the magic eraser....it said it did wonders on acrylic.

put down a big thick towel lay the tank on its face and pour some vinegar in there 100" or mixed it doesn matter.. and use a old credit card to scrap the acrylic off works well thats what I did on my 180 when I bought it

Thanks for the help guys! Dan, This stuff is on there pretty good, are you sure that vinegar alone will do the trick?

Hot water works the best to soften it, then it can be scraped off with a plastic scraper.

Just make sure the tank is not cold before adding hot water....just in case.;)
