A Solution to BBA

[dpatte]

I have been in the hobby for 50 years, but only since I moved to Ottawa have I had issues with BBA (Black Brush Algae).
And until this year I had no cure, but I have found something and wanted to share it.

H2O2 (Hydrogen Peroxide)

The trick is to add 10ml of 3% hydrogen peroxide per 15 gallons of water for 3 days and wait.

I did this to a 75 gallon tank after removing all the fish, but not the plants and it worked great. The article says that removing fish was not necessary, but I have 3 gorgeous Synodontis multipunctatus {?} that I've owned for over 15 years there and wasn't willing to risk them.

BBA all gone, and plants look fine.

I now have another tank with BBA that i started doing tonight, but i have left in the fish. i have started today but with 1/4 the dosage, and will watch if the fish distress, and report.

I've tried peroxide on one of my tanks that has BBA in it.

Both times I negatively affected the cycle.
I guess I may have added too much, even though I thought I had underdosed.

I refuse to use Flourish Excel in my tanks.

There's the One Two Punch as described here.

Hi Blackrose.  Can I ask why?

Hi Blackrose.  Can I ask why?

Every time I used it (underdosed it) I had panda cories die within days.

Both of my tanks with BBA have panda cories in them.
One also has a decent sized group of pygmy cories, which also seem to be delicate.

Hydrogen peroxide is one of my go-to solutions for algae control. Buy it from the dollar store, where's it's way cheaper than anywhere else.

Funny enough I just did a 1-2 punch a few weeks ago and the tank is very close to algae free. I do not do the Excel at the end though as that stuff is so bad. I'll have to spot treat a few areas that didnt have as much flow when doing the treatment but it works really well.

I also under dose my 35G tank with hydrogen peroxide, and the BBA is still there. Should I do a water change before doing it again?
