Help getting rid of BBA

good idea... your light was obviously what kicked it off... as tom seems to be stating it is the balance... that extra light threw off your balance so now you have the choice of upping your co2 and ferts or lowering your light output. lowering your light will be a lot less expensive than constantly dumping things in your tank until you find that happy medium. i would turn the light off for a couple days to kill off some bba and see if it comes back once i add the light back into the equation without the reflectors. that should give your plants a chance to keep it at bay if things are close enough.

also i may wonder what kind of nerites you have or if your params are off or if there may be an unknown contaminant... my nerites seem to never want to leave the water. i have about 10 including olives, zebra and sun.
