Kntry I just finished doing the treatment again.

This time, I used 8 Tbls. in 5 gallons for an hour, after taking out the Betta and my moss wall which does not have any algae. (it's new)

I'll post what it looks like tomorrow.

anastasisariel Results are seen within 24 hours in most cases. BTW, DarkCobra hasnt' been active for a while.

Kntry How long does it usually take to see results?

Wednesday night, I took the Betta out, turned off the filtration and put 4 tbls in 5 gallons with tons of air. I let it sit 15 minutes, did about 90% water change and added Excel.

The hair algae looks a little lighter but nothing outstanding and the BBA is still on the glass.

Should I do another treatment tonight?

nova777 Hi DarkCobra,
I've been having BBA issues for months now and am
on the verge of losing all my plants.So after reading your thread here,
I went ahead and followed your "One-Two Punch" procedure,
(Two tbsp. per Gal h2o2),to the letter.I'm already seeing the algae
turn white and pink.I've never used Excell before,so I used the standard
5ml per10 Gal dose.While looking at the reaction under the light,my
daughter pointed 3 or 4 small fry I hadn't noticed until after the treatment.
I'll post again on this thread on further results and how well the fry do.
Thanks so much for posting this thread.

rawlins06 Just did 1.5 tbsp per 10 gallon on my 20l, 30min later did a 25% water change. There is a lot of pearling and my fish and snails seem fine.

DayOlder I have two tanks both of which I do 25% WC on every Sunday. I alternate which tank I start first and add 2TBSP/ 10 gal of H2O2 to the other tank, also turning off the filter and on the power head. By the time I have the first tank done the second tank is ready for the WC. This way it takes me no additional time and each tank is treated every other week. Since I have started doing this I have quit treating daily with excel, in fact I have not used excel at all and both tanks have remained algae free. I have had no loss of livestock or plants although my octocinclus do not seem to like it. I started this after doing the 1-2.

mot Wanted to chime in that this procedure worked for me as well. I used the 4Tbsp per 10 gallons of H2O2. I removed the fish (5 oto's) and the biomedia from the cannister. Added the H2O2 ran the pumps for 45 minutes. Did a 80% water change. Added the recommended initial dosage of Excel. Let the tank run for about an hour and then added the biomedia and fish back to the tank.

Why did I do it? I had a filamentous algae outbreak after a rescape three weeks ago. The tank had three types, a little bit of staghorn, Long stringy brown algae maybe filamentous diatoms (not sure never ran into this before) and a green thread algae that was growing about 4 inches a day in the high flow areas.

Pretty sure it was all due to disturbing the soil where the Osmocote Root tabs were placed only a couple weeks earlier. Of course I completely forgot about them as I was happily changing the slope.

Here is my observations after the treatment
Same Day:
Almost all algae looked unhealthy by the end of the day. Most of the staghorn turned pink. Brown algae turned grey. Green algae looked a darker green.
Next Day: All staghorn was pink, Brown algae now grey and melting...maybe only 50% of it left. Green hair algae now grey and visibly less of it.
3rd Day: Staghorn is now melting, Brown algae is almost gone...only whitish fuzz left where it was thickest. Green hair algae now grey and about 75% of it is melted.
4th Day: Very little algae left. Anything visible is a grey or white color and looks dead.

Fish: no issues - taking them out I didnt expect any
Plants: Mini Pellia was burnt pretty bad. May lose it but the Flame and willow Moss look fine, Java Fern roots are missing the fine fuzzy appearance when they are healthy. But they were covered in the brown algae so not sure if they were already damaged. No other plants show any negative signs of the treatment.

Plant list: Staurogyne repens, cyperus helferi, Java Ferns, Anubias Nana, varied species of Bucephelendara, HC, Rotala Colorata, AR mini, Crypt Balansae, mini pellia, flame moss, willow moss

Roughrider Update on my nuking this past Tuesday. My BBA is dead and the SAE's are cleaning house on the red stuff. My black fuzz algae is dead and even the oto's are munching away. No dead loss at all. I'll admit though, at about 12 minutes in my old yellow molly was acting stressed.

I was able to pull three of the 4 oto's before the process. All four are doing fine.

Turned off and pulled my cannister for cleaning and used .45 cups (just under half) of 3% H202 and then followed up with a 50% water change and immediately hit the tank with 16ml of Excel.

Two days later I lost my runt Angel that had not been eating for a few days prior - think the stress of the whole process finally finished her off. It could have been that I beat her up during the washing machine/cyclone effect as well... I don't know.

My water quality has remained solid at:
6.8 ph (tested during mid-day c02 injection)
0 ammonia
0 Nitrites
20 Nitrates

Rainer I didn't know about that. Thanks for the warning.

I would suggest temporarily moving your fish... Micro rasboras are very sensitive IMHO.

I would take it out lest you kill your BB.
