nothing ate mine. SAEs grazed on it a bit, but not much. Once under control they may be adequate, but they aren't going to eliminate a problem. There are posts on the forum about black line gobies eating it. Haven't tried them yet.

I got my BBA outbreak under control by dosing Excel 3x for 10 days. There's still some but not much. Been 2 weeks. I had some Threadfin Rainbows that died during this time. Was treating Ick with Ick-Guard at the same time. Can't say it was Excel that hurt them. No other fish seemed to have been effected in any way by the Excel. All behaved and ate normally.

I have used H2O2 to kill it. After it was dead my otocinclus and amano shrimp ate it. But if you don't fix the cause it will just come back. I'm not sure if I'll ever be rid of it in my non-CO2 planted tank....

BBA and staghorn both have a similiar process to clear it up. One of the 40 breeders here has mass amounts of black beard algea. It's the dominant plant. I am tempted to try a diy co2 setup on it to see if higher co2 does clear it up. The only problem is there is not a decent flow of water in this tank.....which is another reason supposedly it will show up.

There is really only one way to get rid of it. Manually remove as much as you can RELIGOUSLY then change the environment so that plants outcompete it.

Algae is omnipresent in all tanks and can never be completely erradicated. But can be kept at a minimum by promoting plant growth.

Sure you can add this or add that to kill it but it will come back again if you don't have good healthy growing plants to combat it on a regular basis.

how about adding elodea or some other fast growing plant to use up the extra nutrients
That is one possibilty. But to get rid of extra nutrients it would be faster to just do a large water change. In the long run just add more plants. A heavily planted tank will IME have less algae problems.

Of course you have to have the proper lighting and CO2 to balance things out.

Nutrients themselves don't cause algae. An imbalance of light, nutrients and CO2 does. As light levels get higher the need for nutrients and CO2 increases. At low enough light levels adding CO2 becomes a non-issue. At higher light levels you need proper stable levels of CO2. Plants grown at all light levels need nutrients, the amount needed is relative to the amount of light.

A bit more info about your tank would be helpful if you want specific recommendations from the folks here. The suggestions so far to remove as much algae as possible manually and spot treat with Excel are the best way to deal with BBA. So is the comment that it will just come back if you don't fix the underlying cause.

Hair algae is difficult to get rid of unless you reduce your lighting intensity. That means less watts or raising the fixture, not cutting photoperiod. You will also need to prune and pull out as much as possible. Once you have it beaten you can slowly raise lighting intensity again.

I found Rosy Barbs to do a decent job eating hair algae. Problem is that they also eat any plants with fine leaves.

Fish that eat algae are more helpful in preventing a mild outbreak from spreading. They don't cure the problem once it is established.
