green spot algae

[gradantanant]

hey all

when I decided to change my background to black cardobard I discovered these little green spots dotted around the back wall of my tank. it was very hard to scrap off and most of it is still there.

I was wondering what type of algae it is and what is causing it and how to get rid of it successfully.

Yep, it's a healthy, photosynthetic algae (though, ideally, you don't really want very much algae). It is a pain to remove (scrubbing will do it after about 10 strokes), but it shows that you're tank has a fair amount of light. Nothing to worry about.

One other method of getting rid of it is a razorblade angled flush to the glass.

Dosing phosphates got rid of all my spot algae problems. The only time I scrub my glass now is for the occasional brownish film.

My brother (apocalypsegold) also uses a razor blade, but I am scared that I would scratch the glass, so I use a credit card. I get lots of fake ones in junk mail and finally found a use for them.

I know what you mean about the stuff being hard to get off. I used to scrub so hard I was worried about breaking the glass and the stuff still would not come off. It just needed to be scraped instead of scrubbed.
