I can't figure out what type of algae this is. I have spent quite a bit of time looking a pictures of algae on the web, but not luck in seeing anything like it. It is black and is it very difficult to remove. I can't even scrape it off with my fingernails. I think I originally got it from some bolbitis I bought at an auction. It is now also on some of my balanese crypts and on my moss.
It does not appear to be a fluffy as the pictures of BBA that I have found online. However, maybe it is a variation. I just don't know....
If anyone know what it is and who I can get rid of it without killing my fish, shrimp, and snails, please let me know.

37g planted, 11g planted, and three 5.2g planted shrimp tanks.
Excel right on it. what i do is turn the filter off while im doing water change. also turn off the powerhead and when the water is still apply right on it. wait like 10 mins or less and then fill. it worked for me, normal or twice the recommended amount but no more (or you will also kill fish like i did =/ )
i now add excel on a continuos base to keep it away...

looks like brush algae to me. cut the offending leaf off at the base. I have read somewhere that hydrogen peroxide works using it the same way Damion described for the excel.
Francine Once you go Dutch you can't stop trimming.
+1 for BBA, black brush algae. excel directly squirting on the affected area using a syringe as mentioned is highly effective. I have also done 2x the recommended dose overall in the tank and that can do the trick as well.
Also you might want consider gradually increasing your CO2. BBA can frequently occur when flow is decreased due to increased plant growth and also the increased plant growth uses more CO2.
Yes, I'm working on it too

I've used peroxide on other mosses without incident. I've also applied it to plants above the water line during water changes. Just don't let it sit too long.

I did a double dose of Excel yesterday, but the BBA seems the same. I did the whole tank since I was worried about appling the Excel on the fissidems directly. Does it take a while for the BBA to die, or should I give it another double dose?
Also, how often should I dose Excell to keep the BBA in check? Should I do a double dose once a week? Or just a regular dose once a week?

I read this on another forum, but it seems like a lot of Excel.
Stop your filters so there's no water flow for about 10 mins. Treatment should be continued for 14 days with daily overdoses, ideally just before lights off.
Do change at least 40% water a week during the 2 weeks treatment too
Before I keep up this intensity of Excel, I thought I should check with the collective intelligence of GWAPA.

I have found that it only takes 3-5 days of treatments at 1ml/10g daily to kill BBA. Treat until the BBA turns red. Other algae can be more difficult to kill.
