Do all those Biological Additives out there work or not?
I read about Bio-Spira product; it works instant. Not sure it is true??
Some says bacterias need oxygen to survive, but those bacterias are enclosed in bottle. Not sure how they can survive.
Do anyone have any experince on any of these products or brands will work for Biological filter?
Thanks
