I have an acrylic tank with four nasty patches of coraline algae.
Scraper will not remove them. All I am doing is adding scratches
to the tank (on the front panel!!)
Anybody have advice on how to remove coraline growth like this from
acrylic.

I used a old credit card with success on acrylic before

I know the stainless steel blade on the "Flipper" works great on glass,but don't have any experience on the"Flipper" ABS blade with acrylic.

I am using the Kent spraper with the plastic blade. I have been told by
a friend who does tank maintenance to not use the stainless blade
on acrylic. It will create more scratches.

If you have the time use a toothbrush and your finger nails

not to lecture but I'll bet next time you'll clean more frequently. Coraline is easy to remove when it first starts.
If the tank was empty, vinegar works wonders.

Scrap pieces of 1/4" acrylic freshly cut worked well for me

Yep, that's what I have to do in the acrylic sump. And it is much easier if you clean at least once a week rather than let it build up.
