Excel as a treatment for BBA? Experiences?

[joan]

Initial dose: 10ml in my 20G (5ml per 10G)
Thereafter: 5ml (2.5ml per 10G)

Dosed with lights on.

The BBA is now completely gone.

I am about to start dosing excel in my 100g tank to rid the tank of the dreaded BBA. Should I dose 2x, 2.5x or 3x the reccomended dose?

Should I be dosing 50ml per day for 10 days as I have a 500ml bottle.

Thanks,
Dave.

Yes, that should work. If you have a UV sterilizer, make sure that it's turned off.

i have a 15gallon tank with this stupid BBA ...grrr when will they just stop comming back. anyways how much would i have to dose to get rid of them?? im thinking about 8-10ml?? for the first 2 weeks everyday. would this be enough??

[pk-sd]

Just go with three times the recommended dosage for 2 weeks. It should do the trick. Also increase the amount of CO2 if you can.

Mine every once in a while tries to make a comeback, but 2-3 days of treatment takes care of it.

That's really high dosage actually. See my post above for what I dosed.

Hello All,

I started using Flourish Excel to combat BBA and also hair algae. On the first day, I tripled the dose to 60ml for my 40 tank. (I have a 40 gallon, 5ml per 10 gallon)

Anyway, lost an octo, 4 big cherry shrimps, and 1 neon. I changed some water, backed it to 50ml and everything seems to be ok. I must say, this stuff really works and it's only been 2-3 days. The BBA is not turning red like for everyone else, but it turns white and I can see it's dying off. Hair algae is slowing shriveling away. One thing though, it seems like my riccia is not as healthy anymore? It's also turning white and only green at the tips as it continues to grow.

Anyone else have this problem? Thanks.

Riccia, L madagascarensis and a few other plants died back at higher dosings.

Killing your fish is not a wise method

Try focusing on why the BBA is there to begin with rather than killing your livestock.

This will provide better plant health.

Trimming the plants, clean equipment is still needed even if you kill it with Excel. The infested leaves still look bad afterwards.

And if you stop dosing without adding more CO2, the BBA will come back.........

Thanks Tom, will do. I wanted to just use the Flourish to "clean" my tank and now I'm going to get a full CO2 system.

[plantbrain]

Excel does not hurt and it does address the CO2 to some degree.........

It's good and not a snake oil treatment for BBA or other algae.
But if you use CO2, use the CO2 __correctly__.............

Don't feel bad, everyone from myself to Amano louses up CO2 every so often.

hey guys i have a 15gallon and i dosed 10mls on the first day and 12mls on the 2nd...but the BBA is still the same as usual after the 2nd day... and i know im dosing lots, should i reduce it down to 8mls?? because i dont want the copper sulfate to get to my shrimps

[markstr]

Just to let everyone know, I am in to day 16 now,
and pretty much done with the 3x OD on this..
90% plus of hair Algae is gone . (was everywhere)

Just upped CO2 to high 40's to low 50's ( Tom- Plantbrian)
Ferts in check..

Two things though going on: Little Cloudyness of water,
and just a little bit of small "Green Balls" on Rocks..
BGA or??? Took one Rock out and Toothbrushed them off..
Is the 14 days a Cut off for this or????
Also- Cloudyness of water due to ?? I believe the treatment itself.

[donkey]

Cloudyness is from to much co2

I need to start a similar thread myself. I've been dosing at 4x the recommended amount for over two weeks now, and though I've seem some improvements, I'm not seeing it die off as quickly as many others have reported. Many state they see it changing colors in a single 24 hour period. So, why isn't mine ?

If my calculations are correct, you're only dosing around 2x the recommended amount. Most on the longer Excel thread recommend 3x. I'm taking more of a risk jumping up to 4x (based on all I've read).

Good luck!
Brian.
