    The 'lack of fast growers' track seems to be a plausible problem/solution too, as my tank which has a chronic infestation is a very slow growing tank too.
    While remotely, very remotely possible,............highly unlikely.........

    They are quite unlike any bacteria known..........
    Weeds, insects, fungi, rodents.......every major biological group develops resistence to pesticides...........it's not just bacteria.........

    OK, so I siphoned up the gravel at the affected area, cleaned it real good, did my 50-60% water change and then re-dosed KNO3, 2 days later and still good, looks like I will monitor further before I can confirm anything else.

    Normally I use Hydrogen Peroxide with needle and injecting into the front glass gravel. Do about 6" per day. It will kill the BGA immediately into RED and clear pretty fast.

    Ok day 5 is today, so far so good. BGA kept at bay... Looks like I'll wait till a while longer before giving a thumbs up.

    Btw, wouldn't injecting the affected area with Hydrogen Peroxide cause the BGA to be resistant to it in future, since its gonna be in your tank, won't that cause you to have Hydrogen Peroxide resistant BGA?

    On another note, won't it harm your fishes, the Hydrogen Peroxide?

    H2O2, Blackouts, Antibiotics etc are not needed except for strong cases of BGA, often you can kill it off with good cleaning, water changes and dosing KNO3.

    If not, try the blackout, it takes the same time as the pills, H2O2 is only effective for spot cleaning.

    One of my tanks was with BGA. The BGA on the tank wall was around 15cm diameter and some plants were affected. I had 100% water change last Sunday and yesterday, all BGA were totally gone. Besides water change, the only thing I did to the water was I added some TMG. That's all. Hope it works for those with this problem too. Faunas inside the tank are 2 x SAE, 2 x oto, 5 x yamato shrimps and 3 x ramhorn snails and a pair of ever hungry betta ocelatta. I dont think any of the faunas did anything to clear the algae. So it might be the water change and TMG

    That's interesting. Heh, if there's any fish that has BGA for lunch, I'm sure it'll be a hit in anyone's tank(s).

    Tom, any comments on the 100% WC + TMG here?
