Adding the whole vial of biodigest (bac) should be fine. it's a waste, but so is flushing it. (fwiw, we dosed 1 vial on our 20g nano, here's a write up on the system we use, incorporating prodibio additives and our own mixed C-source
achieved through observation and experimentation at glassbox)
However, be sure to add a dose per your tank size of the optim. reefbooster can be dosed heavily if nutrients are low enough. I would suggest dosing half the recommend dosage to start until the bacteria can low nutrients without excess algae growth from the reefbooster addition.
Also, make sure your params are at NSW and alk is stable before dosing begins...or STN/RTN may occur.
