I have BBA on one piece of driftwood in my 125g tank, but not on the other piece that is so close they touch. None on anything else. The driftwood pieces are two different kinds of wood, and I'm convinced that has something to do with it - there is something about that wood that encouraged that growth of the BBA.
It isn't much, a few dots that range from pinhead to 1/2 a marble, and the amount changes constantly. Nearly disappears, comes back, fades away, etc.
tank is 125g, 72"L x 22" T x 18" D
Lighting = one 48" diamond plate Home Depot shop light with two T8 bulbs, 6500 & 6700
Lighting height above substrate = sits on top of my versa glass tops, so about 22". The center of the BBA area is 7" - 8" from the bulbs.
Color temp of light 6500k, 10k etc = one 6500 and one 6700
Co2 yes or no = no
Lighting period = usually 4:30 pm until 10 pm, when I get home from work. Next week I'll start working from 1 to 10 pm, so the light period will change to 12 noon to 11:00 or so. I don't have a timer & will have to turn the lights on before I leave.
Tank temp = 76-ish in winter, up to 84 in summer.
Photo of drop checker if applicable = N/A
And how extensive is the coverage = A spattering of various sized dots on the extreme upper left area of one piece of driftwood (not the right), perhaps with an 8" radius. Found on surfaces that get light and don't get direct light (the underside of the wood) This part of the wood is also within 7" of the outflow of a Marineland Emperor 400 HOB. perhaps the current & it's oxygen feed it? Other parts of the dw just as close to the light don't have any BBA...
I will add that this had been in the tank for months. Since it hasn't spread and stays confined to small dots on the wood, I leave it be. I don't mind how it looks and sometimes my ramshorns look like they might be eating some of it. (or they are eating around it - I can't tell)
