    Pointers on resolving algae problem

    Well, the brown algae in the last photo is loved by Otocinclus, so just get yourself a couple of them. For the rest, the plants just look like they get a bit to little fertilizer. Add some more, trim the old ugly leaves and your good to go again!

    What exactly causes BBA? Part 2 - Bacterial imbalance

    Haha, he just want to make you think instead of spoon feeding you. I always like his posts on APC, but I guess they're not meant for everybody...

    What exactly causes BBA? Part 2 - Bacterial imbalance

    0-100 ng/L, and I bought 2 gram pills [emoji28] I know also wonder how much is in normal fish food... All other building blocks will be no problem. Just talking water from one of my tanks.

    I got pure B12! Does anybody know what concentrations we're talking about?

    Sounds very plausible Andy! Man will we laugh about this thread in 50 year when we know more [emoji14]

    Could it be both? Damaged leaves release organics, whether it's from too much op too little nutrients.

    I agree, the only thing it could theoratically remove is chelators. But I've never found this to be a problemen running purigen and carbon 24/7.

    What exactly causes BBA? Part 2 - Bacterial imbalance

    Someone at APC forum once tried. He collected samples from hobbyists to see whether there was a correlation between organics and BBA/algae: http://www.aquaticplantcentral.com/forumapc/algae/89126-organics-analysis.html

    What exactly causes BBA? Part 2 - Bacterial imbalance

    IME, it does. And theoratical op should bind vitamins as well. If not, something live purigen should.

    What exactly causes BBA? Part 2 - Bacterial imbalance

    I think you miss one thing. Healthy plants is not only high O2. It's also low organics. When O2 is high but plants unhealthy, there will still be loads of organics -> a lot of heterotrophic bacteria -> B12 & ammonia formation -> BBA.

    Plants grow faster with CO2, so the effect is stronger. Verstuurd vanaf mijn E6653 met Tapatalk

    What exactly causes BBA? Part 2 - Bacterial imbalance

    I've a very low light paludarium water part which does grow BBA. I feed quite a lot because I've Sewellia in it breeding. I do dose micro's but no (extra) potassium. I've noticed that I can grow Anubias in full light in an ADA tank (which does receive daily potassium) and not in this tank. I've...

    What exactly causes BBA? Part 2 - Bacterial imbalance

    I agree with a lot of observations from everyone, bus can anyone induce BBA by simple adding ammonia? I can't... I add ammoniumnitraat and urea daily. Never noticed any difference. Feeding more -> BBA. But is this due to ammonia, I don't believe it. Many commercial ferts got ammonia in it. Would...

    What exactly causes BBA? Part 2 - Bacterial imbalance

    If this is the case, than more flow should help to even out the pH issue and thus less BBA would grow... The ever recommended 10x flow isn't a bad idea in that case.
  15. Yo-han

    What exactly causes BBA? Part 2 - Bacterial imbalance

    High flow or close to the filter where B12 was produced[emoji6]
  16. Yo-han

    What exactly causes BBA? Part 2 - Bacterial imbalance

    I can second this. I always wondered why full ADA tanks never had BBA on Anubias. I think the large filter and the potassium makes all the difference.
  17. Yo-han

    What exactly causes BBA? Part 2 - Bacterial imbalance

    And as far as I understand the subtitles, no filtration as well. And with goldfish! :O respect!

    What exactly causes BBA? Part 2 - Bacterial imbalance

    Thanks for the detailed answers! I don't have the time to read this papers next week but certainly will soon. Looking at the molecule it contains quite some nitrogen, so purigen should have a high affinity for B12. I see a boost in purigen sales, where is my part of the money? [emoji12]
  19. Yo-han

    What exactly causes BBA? Part 2 - Bacterial imbalance

    But still, without organics and only by adding ammonia/urea and B12 do you think BBA will grow?

  21. Yo-han

    What exactly causes BBA? Part 2 - Bacterial imbalance

    In that case, by simply adding B12 I would get a BBA outbreak... Send me some and I'll test!

    Aaah, I missed these kind of discussion on UKAPS. I love it when people search for causes instead of 'dose more ferts and algae goes away'. I've had quite a topic about this on another forum a few years ago: http://www.aquaticplantcentral.com/forumapc/algae/87902-cause-solution-bba.html The...

    Why more algae in filter pipes than outside?

    Controlling GHA on Fissidens

    Any update on this?
  25. Yo-han

    Controlling GHA on Fissidens

    About the ferts, I see fluorinK (only potassium?) And fluorin gro (only nitrogen?). Google doesn't know them but if this is true you are missing phosphate and traces. In that case you can twirl your toothbrush every day, but it will grow back unless you add the missing nutrients.

    BBA Wierdly Disappearing?

    A common mistake, proven wrong over 20 years ago but still this myth is kept alive! All the beautiful tanks you see on the internet are loaded with macro nutrients, either in the substrate or in the water column (or both)...
  28. Yo-han

    BBA Wierdly Disappearing?

    It is probably because your plants are doing better. No longer leaching organics into the water and thus no longer feeding the BBA.

    BBA & SAE

    Don't feed your tank and sooner or later they'll start eating BBA (and moss when BBA is gone). As soon as they learn to eat fish food, they are useless IME.

    Still suffering with Black Beard Algae (BBA)! :(

    I know it is against all the increase CO2 people, but I've never conquered BBA with increasing CO2. I did conquer BBA though. IMHO it is all about organics. Here is a thread from when I was battling BBA. A pristine tank is key IMO. Do not overfeed, keep your filter clean, your substrate clean...

    A full blackout or just lights off for a "soft" blackout

    It is weakened now, so any other treatment like H2O2, excel would hit it way harder than normal!:bookworm:
  32. Yo-han

    A full blackout or just lights off for a "soft" blackout

    Yes, CO2 is produced by bacteria and fish already and nothing really needing it so good to turn it off. Aeration is the most important factor, otherwise you'll uncover your tank after 2 days because of the smell of death fish, because you fish and bacteria use oxygen and without NO2 is produced...

    True! And don't forget to aerate during the BO!;) Sent from my HTC One using Tapatalk

    A full blackout or just lights off for a "soft" blackout

    I've very good experiences with a 3 day full blackout. Not sure about the 'soft' blackout. I think your plants will take a longer beating while at the same time the ambient light might be enough to keep the algae alive.
  35. Yo-han

    Take a deep breath...

    I agree about the more light than necessary but diatoms grow in low light as well. Add some Otocinclus, they love it!

    Unknown algae - please help?

    I can sent you some sodium bicarbonate. You can make a lifetime supply of 4 dKH or 5 if you like with RO water. PM me;)

    Yep, that might attribute for sure!
  38. Yo-han

    Unknown algae - please help?

    I see GSA, which could indicate low PO4 or low CO2. And I see BBA, which is caused by organics (read: dirty tank, rotting material, a ammonia spike). Try to increase PO4 and CO2, and make sure your tank is pristine! (remove every dead leave, dead fish etc.)
  39. Yo-han

    Is this BGA

    Just grab a little and smell;) BGA has a very distinctive smell, very 'organic'. But my guess is that it are diatoms.

    Algae affecting bottom plants... any ideas?

    Agree with ceg4048. 2wpg (of thats means anything at all) might work if everything is in balance, but I don't think you can pull that off without macros. V30 may sound complete, but it doesn't contain nitrate or phosphate. The dropchecker seems quite dark green for that amount of light as well...

    Clarification on BGA or Staghorn

    It's my nemesis too! I think I mastered all algae but BBA. Unless you're willing to lower the amount of light (I'm not) the key is a pristine tank. Make sure all plants grow well (enough nutrients, CO2 etc) remove every dead leave or other decaying matter instantly (at least daily) and do...

    Clarification on BGA or Staghorn

    BBA does not care much for a three day blackout IME. Blackouts kill all green algae quite good, but the BBA is always still there.
