Oh boy so that's what this is, I'm entering into the benificial bacteria method, that makes me a bit nervous as I don't know anything about it and it seemed from what I read that's where everyone ran into trouble, I think it was to do with temps mostly tho? If I keep the temps under 20 celcius and use this gff product would that really help stop bad bacteria growing?It's the opposite approach to using chlorine
Sterile: kill the harmful (and everything else)
Bennies: out-compete the harmful with beneficial
