What removes coraline the best?

[phishcrazee]

This may sound wierd, but I have a real problem with coraline taking over everywhere in my tank. I don't mind it growing on the back or on the sides of the tank somewhat, but I don't want it on the front of the glass. Does anyone have a good method for removing it without scratching up the tank? I've heard using a razor blade works, but thought I'd get peoples opinions first. I was also thinking about getting a pincushion urchin, as I heard they will eat it too.

Elbow grease and a scraper. I used to have one made from a razer blade and a two foot long piece of 1/2" pvc. This was on a glass tank. Acrylic tanks are a different story.

glass = razor blade

acrylic = old credit card

Urchins!

Razors, gotta be careful around the silicone though. My urchin moved everything in my tank that's smaller than itself, so i wouldn't recommend that route, even if it IS kinda funny to see how much crap an urchin can carry around.

Kent Scraper with metal blade works great on glass.

razor blade on glass. Urchins are more of a pain than they are worth. They demolish your tank and don't climb on glass much. Their eating habit can also cause coralline to spread, by breaking off pieces and spreading them through the tank. If you want it gone, go to 250 or 400 watt MH.

urchins are a pain, but they are still fun, mine devours coralline like it's nobody's business. Kinda sucks cos I really like the purples, but it is entertaining to see the pack rat run around, would be hell on frags if you have them though.
