Maybe spray it down with peroxide (wait 5-10 mins, watch it sizzle)and then do a flush of the system (hour soak) followed by some ferts to keep the bga from coming back? Assuming low nitrates triggered the bloom.
hmmm... I was trying to get away from soaking because the substrate is sphagnum... it is going to float everywhere if I soak it.

Not sure if it would work but you could try mixing up a solution of Maracyn-Two in a spray bottle and misting with that several times a day for a week. Or, if you've got things in an environment that can be flooded, fill with water and toss in a pump and dose Maracyn-Two at full strength.
I never tried maracyn-two before but I don't have time to mist it several times a day. I can't flooded it either.
Have you tried spraying a KNO3 solution?
I heard this will burn the UG. What am I targetting 10ppm? or 20ppm?
