I don't have a pic, but I will try to get something tonight, if anyone wants one.

My 20 gallon tank has what I think is BGA. I took this tank down, cleaned it, and replanted it a few weeks ago.

The heater is completely covered with a bright green film (not a lime green, darker). The gravel and some plants are also getting this film, and you can see air bubbles under the film. If I disturb the water a bit by it, the film waves some.

Any ideas? Is it BGA?

Yup, that's BGA. I'd really love to give you advice on how to get rid of it for good, but I'm trying to figure that out myself... hopefully you'll get some help here

I saw your other post. How are your nitrate levels? That seems to be a key point with that stuff. My nitrates are always very low, which is why I assume I have the problem. But I wanted to verify before I started all my research.

the first outbreak I had, my nitrates were very low, barely registering. since then ive done a blackout and made and effort to raise my nitrates. they're around 15-20 ppm. i check every other day, and if they dip I add a little stump remover (KNO3). That was working for a while, but I dont know why it blew up again on me. I know the best way to get rid of it is to make sure your plants are growing, so thats why I asked in the other post if CO2 would indirectly help.

for what it's worth, the first method that worked for me was a real good cleaning, then a four day blackout, then start dosing KNO3 and keep those levels up. it worked for me for a while, but Ive screwed something up along the way.
