I've heard about a few species of fish that eat BBA, but it seems different people have different experiences. I have some anacharis, which is particularly sensitive to Excel, but which I've gradually acclimated to a normal dose; it too is unharmed by this treatment. We have had some setbacks as the article points out, and BBA has thus far been one of the biggest issues. My thinking was that giving the plants CO2 along with my current lighting and fert dosage would give the plants the advantage to out compete the BBA for nutrients. This treatment does work, but it’s pretty extreme. We still use a 50/50 mix of Excel and H202, but these days we spot treat BEFORE the BBA gets out of hand. It may take another half hour before H2O2 is sufficiently reduced. While light does break down H2O2, this is measured in days - even in direct sunlight. There were a few leaves I intentionally did not spot treat with either the peroxide or excel. The video did not show the process taking place, so we didn’t know exactly how much to apply. I've used this treatment many times over the course of the last year. To kill Black Beard algae with hydrogen peroxide, you need to soak any affected plants, decorations, and aquarium equipment for around three minutes in undiluted 3% H 2 O 2. I don’t know if this was needed, but I did it just in case. I initially researched EI dosing while setting up our first scape in 2015, and due to information overload with being new to the hobby, soon lost track. I love my fish like most people love their dogs, so this was really hard to watch and a tough lesson for us to learn. When we were done nuking the tank, it was plain to see that we had covered all the algae with this mix because every bit of BBA was covered with bubbles. Otocinclus, Amano Shrimp, and Nerite Snails won't eat BBA. Please make absolutely sure you do not exceed the percentage of H2O2-of 3% or you may have a hard time calculating the dosages correctly. They were starting to mature nicely, especially some of the more expensive and hard-to-get species like our Cameroon Moss. I wish that video had been more specific.

Nothing really worked and the BBA was still spreading everywhere killing my beautiful plants. At the time I thought we’d made a huge mistake. Light has no effect on the H2O2, only your ability to see what's going on. You can dip other more hardy plants like anubias or java fern. We had tried so many different methods of removal, and the amount of BBA in the tank was so extreme that we were desperate. Only through many more tests in a wide variety of tanks can that be established. In fact, the answers are often conflicting citing variables like flow, nutrients, lights, CO2 i.e. So instead, high flow is required to carry it around the tank, to contact the algae and have some positive effect. I think the beginning of our Black Beard Algae problem started with the piece of driftwood that we used as the focal point. I added 10 Tbsp (2 per 10g @ 50g) of 3% peroxide to a glass, then added another 10 Tbsp of tank water, giving me a 50/50 mix of peroxide/water. Algae builds up some tolerance to Excel, similar to sensitive plants like Vals. All of our plants survived, thankfully, but suffered during the treatment. Java moss was unaffected. A lot of sources claim that increasing Co2 helps against BBA, but that has never worked for me. I put in the Blackbeard treatment from a bottle I bought from the … Save my name, email, and website in this browser for the next time I comment. But when using this all out method, you MUST remove the livestock. Thanks again for sharing. Not any that I bought. The enjoyment of this hobby is gone. Like I send in my original post that I tried everything. In this case, the H2O2 treatment followed by a single, sudden Excel spike is enough to quickly finish algae off. This has worked very well on filter components, the top of my heater, and on driftwood. We did not add fish until all the BBA was gone. We are considering a bottom feeder besides the shrimp, but haven’t decided on what yet. Then I use a syringe to squirt Excel onto the BBA under the water. I guess the takeaway is that if you have a situation like we did where BBA has grow out of control, this method will eliminate it. I admire his work and dedication to the hobby. Livestock: At the moment we have 15 Chili Red Rasboras (Boraras brigittae) and half a zillion Red Cherry Shrimp (Neocaridina sp.). etc. #4. nyleve. The effect of any chemical is determined by: Concentration * Flow * Time. I recently set up a freshwater DSB tank which is about 50% planted with swords and crypts. Other solutions may damage the surrounding aquatic life in the tank or throw off the water's PH balance. They were swimming around and checking out the algae, but they were all dead 2 hours later. How long do you wait between the First Punch of H2O2 and the Second Punch of EXCEL treatment? I was about to give up and start all over again from scratch till I read somewhere that OXYGEN kills BBA, so I added air pump connected to a timer that starts exactly when the lights go off and stop when the light turn on. 3 mins; Anubias? You can read about it in the article I wrote right after the treatment. I use both Excel and H202 to treat algae when necessary (i also keep plants,shrimp,snails and fish in those tanks). So sorry for your loss. I then wait 15 to 20 minutes before adding water back to the tank. Obviously that was not enough. I get BBA even though my pH and CO2 levels are kept steady via a pH controller. I highly recommend that you remove all of your livestock first. The only success I've had is with hydrogen peroxide particularly when I use it for spot treatments. A no time did my fish seem stressed (mostly tetras and a few platys), but I did add the recommended dose of Stress Guard, just in case. I would advise not to dip the moss ball since its pretty much bunched up algae. No further large doses are necessary in this case. By Marios Alexandrou on August 8, 2018. The algae should turn red, then greyish white, meaning it has died. This worked and nothing suffered from it. It finally started to look like we wouldn’t have to replace our hardscape after all.
