I don't test, so I just want to know some solutions to solving hair and thread algae that worked for you guys. It's so annoying on moss. The moss I got was infested with this and now I can't get it out. I'm on the verge of throwing it out. :(

EXCEL!!!!!

Read up on over-dosing it. In a 29 gallon I dosed 5 times the recommended amount daily without any problems. Took about a month to totally wipe out all traces of algae and I had it pretty bad. Hair, thread, fuzz, bba, bga, you name it. Ugh.

If you have good growing conditions then you might want to extract a few small pieces of algae-free moss and culture those.

I've also squirted Excel directly onto Taiwan and weeping moss while spot treating algae in a tank with no ill effect, so that may be an option. But I'm pretty sure that a dipping it into pure Excel (in a bowl) will kill the moss along with the algae.

You are fine just adding it to the water. Some people spot treat but I don't think it matters. Didn't for me.

Also, once you solve your algae problem if your fert regime is in order and CO2 is plentiful, you can stop dosing Excel and algae won't return.

I have not had to use Excel in many months, which is good because it's expensive!

Just about a week ago I cleaned up my tank, got rid of as much algae as I could, dipped anubias and Java Fern in bleach water, and replanted the good plants I still had, plus some that I purchased here and on another forum. Then I doubled the after-water-change dosage of Excel, waited three days and dosed it again. Now the remaining algae is all either white or red - dead or dying. The only cost was that it also killed all of my vals. But, I was kinda tired of them anyway - they reproduce all over the tank unless vigorously culled every couple of weeks.

Here is a good link to do it Eliminating Algae with H2O2

I have used this method, turn off filters, No water movement other then sticking my arm it to spot treat areas. Let it sit of about 20 minutes and then do a 50-75% water change. I did this ever week for about 2-3 weeks and it took care of hair/thread algae. I didnt have shrimp in the tank at the time so use caution and I dose about 50-55 ML in a 55 gallon tank

I'm going to try the H2O2 method tomorrow. My thread algae is just getting out of hand. I pick quite a bit out on a daily basis and it just comes right back.

I'm worried that it won't get all the algae since it is really deep into my moss. I may take the moss out and place it in another bowl and add extra H2O2 at the risk of killing my moss.

That's what I did. I have a huge freaking clump of thread algae in my Taiwan moss. I put it in a bowl (1 cup of water) and added 5 mL of 3% H2O2. It looks fine...so far. I'll let you know how it goes.

Nevermind. My lights just came on in my tank. I did 2.2mL of H2O2 per 1 gallon of water, so ~22mL of it in my 10 gallon. 95% of the moss in there is dead/dying, the anacharis does NOT look good at all. Curiously enough, in the bowl with more H2O2, the moss looks great.

The clado and thread algae in the tank are quickly dying and turning all slimy. This is probably within 20 hours of me doing the H2O2 treatment. I used a syringe and applied it to most of the affected areas with the HOB filter running. Then after 10-15mL of spot treatment, I added the rest in in a fell swoop.

After you added the H2O2 to the bowl containing the Taiwan Moss, how long did you allow it to soak? After the soaking did you just rinse the moss really well with regular tap water before returning it to the tank?

Did you happen to have shrimp in your tank? I'm holding back on using it directly in the tank due to the shrimp.

About three hours. I forgot about it while I was doing the minor WC on my larger tank. When you do it, I'd let the large tank sit for about 30 minutes and do a 40-50% WC instead of 25% like mine (I did a smaller WC because I had lots of thread and clado algae...not a good idea). I just checked again, the moss looks happy as ever in the bowl, but dead in the tank.

As for shrimp, I'd take them all out before doing the H2O2 treatment on the entire tank. You can do the inverted soda bottle w/ an algae wafer trick to get most of them out.

The clado in the tank is getting all slimy now, MUHAHAHHA! A guppy perished too, however. But it was either the H2O2 treatment, or a whole-tank bleach.

Thanks for the advice. I'll do that tomorrow afternoon. Will take out all my shrimp, Gold Mystery Snail, and Clown Pleco. The other snails can stay in there because frankly, I don't want them. Came home after the weekend and found a HUGE number of babies.....no clue why.

Gave it a try today with good results. I let the moss soak for about 2 hours and rinsed it off really well. About three hours later I noticed white strands of dead algae in the moss ball. There was a small amount of moss that died which was mainly older moss toward the bottom of the ball.

This is a good method. Be sure to give it a try on smaller pieces before going full scale.

Thanks a bunch Epic. You saved me a lot of headaches!

Heck yea! My tank is algae-free (for now).

My anachris suffered badly. All the leaves stripped off the stems. Only the very tops are green! =/

I have a bunch of extra, so I'll re-plant tomorrow and see if I can salvage the tops. =)

H2O2 = GREAT TECHNIQUE! At least for Burks and I...try it before a full-tank bleach.

I have a newly setup 10 gallon that has been a constant battle with bad hair algae. I tried the h202, upping my co2, adding more plants, everything I read to try, then I got some Excel. Algae stopped spreading after one day of a double dose, then has slowly died off the last four days of double dosing.
