Green spot algae

So, I have a green spot algae problem. I've tried limiting light but my tank sits in front of a window, and even with blinds closed it still gets sunlight. I've tried brushes, I've tried the magnetic cleaners. Nothing works. Any of you had similar problems? Solutions?

Yes, I have had it in patchy masses and brown algae too (different problem). I got an otocus, a golden and a green chinese algae eater. The oto cleans the leaves of the plants like a hoover. The chinese eaters handle the rocks, gravel and some of the sand substrate. It's crystal clear now. Whenever the tank looks pristine, I put in some algae tabs or combo tabs until I see it starting to reappear. Then I stop the tabs and they earn their keep. It's been a beautiful relationship. Best wishes!

I've had little spots of it here and there occasionally. I just use an aquarium scrubber pad and a lot of elbow grease. You need to catch it while it's "young" before it really sets in or it's super hard to scrub off.

150 Gallon - Mostly American Cichlids
135 Gallon - Angelfish Community
75 Gallon - Odd couple (Polleni/Angelfish)
55 Gallon - African tank
20 Gallon Long - QT
10 Gallon - Empty

Like Jeaninel and Willow I also get the green spot algae. I keep otos, SAE's and a bristle and while they do their jobs 24/7 I still get the green spots here & there. As Jeaninel says, get them while they are still starting to multiply or they are really tough to remove. Never tried the credit card trick, nice Willow!

If you don't stand up for something you'll fall for anything...

I have gift card I used up to get my new camera the other day...I'm going to try it. I've tried just about everything else. I wonder if a windshield scraper might also work...

I use a scrubbing pad or the rough side of a sponge (you know, the part that's not yellow) feel free to scrub pretty hard when you try to get it off.

I have the same problem as you, tank by a window, blinds closed light still gets in. I had algae before but then I did one very thorough cleaning and it hasn't come back yet.

Try throwing a few pond snails in there, or maybe a fish that can help remove it.

If all else fails try using a razor blade.

One 10 Gallon - One White Crayfish
One 15 Gallon - Baby Bullfrogs

i've used the razor blade too,the only trouble i have
is that one of the tanks is a bow front,so on that one i use the card.
i can't put an otto in the big tank now because of the cichlids,they'd tear
the poor thing apart.
