What do you use to clean the corraline algae?

I am using a blade, but I am leaving scratches all over the front side :(

I've never had a razor blade scratch glass. I use these. They're not cheap but they are widely recognized a doing a great job. I also have the scraper attachement. You just super glue it on. The magnet on these is so powerful that I almost never need the scraper.

You shouldn't be leaving scratches with a razor blade. You can try a credit card, it won't scratch the glass.

I used a metal scraper for the glass. They also sell a plastic one also. The metal have a round edge not sharper like razor blade.

I've been using the Easy Blade mentioned above also. It really works well!

I use THIS (http://www.thatpetplace.com/pet/prod/197947/product.web) with the steel blade.

Nothing beats a razor blade though.

I am using the same one like the picture above, thanks for the picture Pmolan. It is leaving scratched all over my glass. It is a 10mm thick glass..

Hi, I use a MAG Float with a razor attachment super glued to it. The blade is held by one screw and a second screw allows for the pressure on the glass to be adjusted. The holder keeps the razor blade at a 45° angle which will not scratch the glass. My aquarium is starfire glass on 3 sides and I have not had any scratches using this product.

I'm mostly using razor blade, if not a thick layer of coraline. Always new blade, and applying not much force and keeping it at small angle to the glass. Starting with certain larger angle (the hand is farther from the glass), it will leave a scratch marks, or if a force is applied.

Kent scraper (on photo above): plastic didn't do the job, metal - bent during first cleaning of hard coraline, impossible to straighter absolutely right.

Now using plastic paint remover from hardware or dollar store (white one) for a thick coraline, razor blade in most of cases, and regular use of magnetic cleaner helps with preventing coraline accumulation.

Metropass plastic card doesn't do the job, and have no supply of disposable credit cards :D

I find that if the blade is new out of the bag, it is perfectly straight. As soon as you lay it down or put it away, a corner gets bent slightly. I see how that can cause scratches. I find that if it gets bent slightly, I can unbend it. If I cant I flip the blade upside down so it is a U against the glass instead of the upside down U.
