Getting rid of coralline algae

[taylapong]

Hey guys, as much as coralline algae is good on the rocks and all, how do you get rid of them on the glass if they start growing there? Don't wanna scratch the glass... lagi worse if it's an acrylic tank!

They can be scrap off the glass wall with a credit card.

Sallylightfoot crabs will eat coralline algae once they have finished up with other algae, even those on the glass. If you are unsure about crabs there are always urchins.

i have a tuxedo urchin that chows down on coraline algae on the glass.. but it still grows back... the best way is just to scrape it off...

if you find a credit card is too difficult use a razor blade but with care...
