    You might check out the discussion at The Skeptical Aquarist which is most detailed. I have never tried any of the recommended remedies but they all seem to have a sound theoretical foundation which is fine if the theory is sound:)

    From what I've read, BGA usually shows up if your NO3 (nitrate) levels are low. Do you know what yours is at? If low I would up to 10-20ppm, keep CO2 up and possibly blackout your tank for a few days.

    Are you sure that is Cyano/BGA? It doesn't look like typical BGA.

    Try dosing erythromycin. If it is BGA that will kill it.

    pull out as much as you can physically remove. turn off your filters and any powerheads then with a syringe, spot dose hydrogen peroxide and watch with joy as the bubbles form and your algae disappears.

    this will help to eradicate the algae but will not prevent the original cause. i have to agree that it doesn't look like typical BGA but the H2O2 should work none the less. good luck!

    That's Rhizoclonium, not BGA. Excel will help, decent CO2, Amano shrimp, SAE's love it(most shark like Labeo/Barbus species love this algae genus), a few good water changes etc. Antibiotics do nothing to green algae.

    The second last photo appears to be cyano/ blue-green algae. I never had a problem with this bacterial algal bloom until recently. My tank has CO2 and EI dosing. I added some more fluoro lights along the front of the tank and within days i got persistent blue green algae. I read that it is due to low phosphates poor current low nitrates. I had this bloom at a high current area of my tank and all my nutrients are in excess. Hence my algae was a light problem.
    I did not want to remove the light so i added some stem plants to provide shade and this did the trick!
    Tom says 95% of algae problems is due to CO2. This may be so but it is much easier to control algae issues with light adjustment. Adequate CO2 combined with moderate light should control 99% of algae.

    I am not sure sure its Rhizoclonium, Rhizoclonium seems to be composed of fine hairs, which doesnt really look like in my tank that but maybe it looks this way because my tank has high current and it weaves itself into a fiber.
    you might be right, its not blue green algae, but i wouldnt know better, as mentioned before, never had problems with algae before.

    but here is the thing, all the other plants are spotless in this tank - it has mostly Anubias HC and moss, the anubias dont have any kind of algae on them and its a relatively a high light setup - around 150 throughout, i can lower the light more if i want to.

    my drop checker is almost yellow, i did recheck it several times, nutrient levels are good, co2 distribution is great via misting, good flow, around 1000gph for a 60g cube.
    I am really pretty sure it cannot be CO2 or nutrients.

    I have amanos and otos, will add more amanos from the other tank, i never saw the amanos eat this though

    I am going to try to manually remove it with a toothbrush and change the cartridges in my filters, also, Spot dose excel or dose the whole tank?

    I find it weird that i have this algae, my bigger tank is less high tech and has poorer co2 distribution yet even there i never had any algae problems.
    Thanks for the input.

    your second picture is no bga, i'm very sure , because i had bga in different colours and after a erytromycin dosis they where gone and never saw them back. I think your light is your problem, to much i think. Something is limiting, reducing your light is much easier to solve your algae problem. You can use excel, spot dosing is more efficient.
    Also do some water changes and good vacuum cleaning

    I had this stuff for about 6 mo hard stuff to get rid of. I finally beat it by upping ferts, making sure co2 was good, 3 day blackout with peroxide at 0.5 ml per gal with daily 50% wc. Peroxide dosent seem to do much enless you do the black out with it. My problem was low ferts and too much light. Thanks for the help with this Gerryd when I had it.

    well the main problem is that i didnt know that this wasnt bga, i assumed it was and didnt even bother to clean to manually - i just thought erythromycin is going to kill it.
    I started to suspect that it might be something else, so i posted the pictures! thanks to Tom I now know its Rhizoclonium - which i honestly havent read anywhere about earlier.

    I cleaned it up with a toothbrush now, hopefully its not coming back.

    Lowered light to around 100µmol, switched out my cartrige filters - should be good now.
    will dose some excel just in case, also added some amanos from my other tank.
