Removing coraline off of glass

[Delphinus]

I use water and a razor blade when cleaning out used tanks. It's smaller so you're better able to focus on the whole length of the blade pretty easily (ie. for avoiding scratches). I'd be afraid of scratching the glass by using a paint scraper or spackle knife.

In a pinch, use vinegar instead of water, it should help soften the coraline. Once you get under it though it tends to flake off pretty easy.

The last one I cleaned I filled with water and some vineger then let it sit for a while and used a razor blade to clean it up.

Thx guys, i was going to use water as well, but a razor blade? thats a pretty small surface area and the tank is 5 feet long (lots of work). Oh well i guess if u want it done right then u gotta do it the hard way. Yea i was thinking a spackle but forgot the name, lol.

I personally went to Canadian Tire and bought a glass scraper. (Bennet brand name??) Anyway it's a retractable blade and handle assembly. The handle is all plastic and the blades pop right out easily and are about 3 inches long. Works great, clean tank, pop blade and rinse the whole unit. Good for next time. bought a pack of refill blades too. I think the whole shebang was about $5.00 or so.
