What is this algae?

[Fishman007]

Ive had this algae on my walls for a while and cant figure out what it is, its hard to scrape off even with a razor blade.











(its the green stuff that looks like green coralline)

That's what it is. Its the start of coralline on your glass. If you get a magnet and clean the glass every other day it wont show up.

if u dont clean ur does it grow like hair? like brown hair?

Coralline algae comes in many colors. The round spots of hard to scrape color are a dead giveaway.
What melosu58 was saying is that a gentle scrub every other day will help prevent it from forming in the first place. So, razor blade it off, and run your mag cleaner across the glass every day or so, and it shouldn't come back too easily.
As for the hair question, coralline algae is tough and brittle. There are a few varieties that will form branch or plate like extensions, but if hair algae grows over it, that is just because it's an easier surface to grip than bare glass.

yes but i have an acrylic tanks so cant do that :/

 

[MacDracor]

There are scrapers designed for acrylic. Usually made from nylon, I think.

i have one but dosent really do the job

I use this scraper made of acrylic. Works great as long as you make sure to hold it tight & make full contact on the acrylic otherwise you can scratch your tank.

 

[Bosnianblood69]

is that homemade? and how does it work?

 

[Keithhjs]

No I got it from a guy who sells them. You just hold it at about a 60 degree angle and scrape. Mine needs to be sharpened though. New the beveled edge looks more pronounced. All you do is sand it with a block to re-sharpen it.
