As the title says... Will mosquito dunks or azamax kill Bennie's in hydro? I'll be using one or both methods to fight fungus gnats if is there any better ways. Only running hydroguard now for bennies. Want to try great white or real growers recharge, possibly brew some Heisenberg tea. Not 100 percent sure which beneficial bacteria approach I plan to take yet. Any recommendations which beneficial bacteria I should use in dwc? Just great white or just real growers recharge or brew a earthworm casting tea or a tea with ancient forest soil like Heisenberg recommends?
