Continued algae problems
Can anyone tell me what kind of algae this is and what I should do about it? I am guessing its hair or thread algae, but I am not sure.
Basically, its brown. It starts out as a single strand or two that grows several inches. Then overnight it blooms into dozens of strands. One even got caught on a fish for a little while. I removed it ones during a water change but it came back. Any ideas?

Hair algae. If its brownish its probably black beard algae.
Dont remove it by hand while its alive, that spreads the spores throughout the tank
You can use hydrogen peroxide in a syringe or turkey baster and squirt the algae directly. Dont exceed about 3ml/g per day.
Some people have success adding excel as a preventative, but a stable co2 source is better, and what Ive had success in conjunction with the hydrogen peroxide treatments.

The easiest way to get rid of it is to break up your light cycle. Algae needs long light periods for photosynthisis. Breaking up your light cycle will stop it having enough light to spread.
I have eliminated Black Beard altogether by having my lights come on for 4hrs, off for 3hrs then back on for another 5hrs. It takes time & your plants won't grow very well, but the plants will survive while the algae slowly dies.
Once the algae is gone change the type, intensity or lighting period to make sure it doesn't come back. Or you might have to look at your fertilising shedule. It's possible that you are dosing too much.If you don't succeed, give up & go to the pub.
