Removing coralline algae from the front panel of a bowfront

[c_johns89]

Hi everyone,
I have a 72 gallon bowfront tank and I've noticed small patches of coralline algae starting to grow on the glass.

What's the best method to scrape it off, without scratching up the glass?

I'm most concerned about scratching the curved front panel. I've seen a few different methods ranging from using razor blades, old credit cards, and urchins. Just wondering what has worked for others, especially those with curved glass panels.

Cheers!

I put an urchin in a 20 gallon over night and it almost wiped out all the Coraline algae so I'd recommend that!

I always used a razorblade. The key is making sure the blade is flat to the glass (side to side cleaning). Being angled or up and down can and/or will scratch the glass

Mighty Magnet with algae cutter bag option. Not cheap but worth every penny. Only thing I use on my acrylic cylinder tank but good for glass also.

I had a 72 bow and a standard razor blade flat against the glass moving horizontal across the front always worked great for me.

Razor blade is the way to go - but if you catch an edge you can and will scratch the surface....so it's slow and steady FTW.

I've just cleaned off an old credit card and scraped with that.

FOSHIO Plastic Razor Blade Kit. Includes Two Scraper Tools and 100 two sided blades. Available on Amazon. Just be careful you don’t pick-up sand with the blade, and pull back and swish the blade, so the Coraline doesn’t Scratch the Glass.
