I scratched my glass

[Schmidt Aquatics]

Kind of sad. My Nano Flipper magnet scraper has been scratching my front glass quite a ton inside.
Is there any way to prevent scratches? Do you guys just live with it, or have you found a way to prevent microscratches? Makes me want to go get a whole new tank..

I had 2-3 magnetic glass cleaners scratch two of my tanks. I don’t know why, really. Maybe glass is more fragile these days because this had never happened before.

I took one of the magfloats and stuck a kitchen green pad on it (unused of course). I use that for my daily cleaning on the front glass. It does prevent most of the algae but every 2-3 weeks you need a bigger clean.

I use my Tunze cleaner for that, but I am very careful and I go slowly across the glass.

About the scratches I have already done, I figure when (if) I ever do a start over, I’ll just turn the tank around (no overflows).

Low iron glass is softer than float glass...so yes they scratch.

I use exchangeable razor blades on a stainless steel scraper, it will never scratch the glass (if done properly)

One of the parts about keeping a reef tank I've been dreading - big thick-butt razors with hardened steel suited to leveling a flat surface.
Anyone tried going the more disposable route by employing ye old'e DE razors as they will be able to press much flatter against the glass/springy and more forgiving of point loads as the edges are dented and disfigured. I'd assume that would translate into being a one-time clean per blade ordeal, but $8 for a pack of 100 blades...

No idea why anyone would use any cleaner other than the Tunze, it's the closest to scratch free as you'll ever get and has the thinnest profile too.

The Flipper magnet is so strong, that it happens eventually. You have to be so careful when you get near the sand line or it will pick something up and scratch all the way across your tank. I already replaced one tank because of it.

Now I use the Tunze Care Scraper. I am still extremely careful, but no scratches yet.

That's got nothing to do with it. I've seen all types of glass scratched from magnet cleaners. I learned the hard way about 15 years ago. A magnetic cleaner will never go near my tank.

If small snail shells , sand or other debris gets under the magnet between the glass it will scratch .
the only way to guarantee it is not to use them .
I use a new razor blade most times

 

[MichaelReefer]

All it takes is one grain of sand.

 

[Townes_Van_Camp]

I use a new piece of white Scotch Brite to clean my glass along.with a replaceable razor on a long stainless handle for scraping.

Never scratch glass.

Barebottom tank...problem solved.

Mag floats and others will scratch without having any sand on it. That’s what is so frustrating.

I've never heard of a Tunze Care Magnet with the plastic blade ever scratch a tank - mine never has.

You have to be careful with metal blades, I use a new blade every time with those devices. it's worth the 10 cents.

I’m not 100% sure the Tunze has scratched anything but I think it has.

I have never used metal blades on this tank.

I NEVER EVER USE Magnetic scrapers after seeing My friends tank who did and had Some many scratches. I use elbow grease with paper towels and an acrylic tank sponge works GREAT> Good luck.

My flipper caused all kinds of micro scratches in my bare bottom tank. Not sure if it scratches when it is flipping or just normal scraping. I threw it in the garbage and only use magic erasers now.
