How to scrape stubborn GSA?

Hey guys

I had GSA that's been on my glass aquarium for months. I bought some razor blades but they're soft and don't really catch on for scraping action.

It's a 180g show tank so I don't want to scratch the glass. What should I use?

If you don't want to use a real razor blade, try a magic eraser (aka melamine foam). Just buy the original Mr. Clean magic erasers, do not buy the scented versions. I'll use one block solely to clean algae off the glass 4-5 times, then swap it out for a new block while the old one is used for household cleaning. Magic erasers are considered non-toxic, and work very well for cleaning algae off the glass. That said, I would not use it to clean hard water spots or lime/salt buildup - the repeated heavy scrubbing can cause the foam block to disintegrate. Just use light pressure to clean algae and there are no issues.

Another (safer) option is plastic pot scrubbers. Little harder to get into the corners, but no risk of scratching glass or breaking down from heavy scrubbing.

Of course, to prevent scratching with either of these products, just make sure you don't trap sand or grit between the foam/scrubber and the glass. That trapped debris can scratch the glass.

Kent scrapers are designed to scrape coralline algae from reef tanks, and they will work on GSA.

Is the GSA out of the water? What you could do is very carefully put vinegar on it and let it sit for a couple of minutes and then try to scrape.

Getting paint off window glass is a common item with common solutions. These use the cheap and simple single edge blade and work very well as long as one is aware of the need to use with care around the silicone. Instead or running left/ right when near the corners, go up and down while using a finger as a "bumper" to keep the blade out from under the seal. Keep in mind that the tool is only as good as the user!

Hi guys thanks for all the responses.

Is it okay to use metal scrapers on glass?

really? a razor blade doesn't work? maybe you gotta angle it more perpendicular. but I get it, a razor blade is unwieldy. How you tried a simple credit card? just angle it out more to get a more aggressive scrape. and it's plastic, so you need not worry about scratching glass.

Paint is a very hard item after it has set and dried for years. It is very common to want to get it off glass, so these scrapers are designed and used specifically for removing tough stuff from glass.
Seems hobby folks are a bit slow to look at what pros use for things like cleaning glass! The difference in what we do and what the pro does is that we are very prone to being cheap and not changing the blades when they get rusty. We do need to keep a stock of cheap blades and change them, so that we are not using a rusty, pitted blade that doesn't work very well.
If you use a rusty blade with jagged edges or tilt the corner into the glass, one might scratch the glass but my twelve year old did the glass on rental places without scratching, so there is hope that an adult can use a scraper.

Another vote for the Magic Erasers. I use them on glass and acrylic and they are very effective.

+1 for magic erasers. +1 for Credit card to get down the front of the glass below the soil line. + 1 for new razor blade on proper scraping tool to get those hard to reach spots behind background plants and in back corners.

I'll add a vote for melamine foam. It's what the Magic Eraser sponge is made of. I buy them from Amazon for a fraction of the price of a Magic Sponge. Most of them are just a white foam block without the layered center piece that a Magic Eraser has. I keep a brick of them under the kitchen sink.
