Sometimes an old drivers license or expired credit card works pretty well as a scraper. (First test in an unimportant area to see if it scratches.)

Even credit cards / drivers liscense if not held at the right angle and pushed straight can leave marks....been there done that......

Or maybe a teflon spatula could work. Seems like sometimes what actually does the scratching is the crumbled coralline algae that gets trapped under the leading edge of the scraper.

I dont know how severe your coraline problem is but the only thing I do is to stay on top of it, so when you see a new spot either hit it very carefully and slowly with the credit card (what works best, ive found, is something like a blockbuster membership card...not quite as hard as a credit card, but still firm) or else the good old fingernail

I can't find the link anymore, but on reefcentral.com a little while back there was someone complaining about the same thing. They ended finding a little brush (which I spent half the day today looking for btw). I guess it'a a brush for washing dishes, but it's powered and the front end spins. People there said it was acrylic safe, but I'd test a small spot first to make sure. I think it was only a few bucks, but I couldn't find it at wal-mart or target today, unless it's not by the cleaning supplies which it should be. If anyone else knows who makes it and where I can find it post up, it seemed to be really great.

I could use that link, too!

I found a link to it, but it's just at amazon. Apparently they are tough to come by in stores. The further out you go on the cone head, the longer and softer the bristles become. The batteries are inside the handle in a sealed compartment, though I wouldn't want to store it underwater. I'd likely take batteries out between using to help reduce corrosion. Lots of people said they liked it, but try for yourself in a hidden spot first. Hope this helps.
