Read About Choosing Biological Additives

Help make your regular tap water safe for your fish by adding a biological product beforehand.

Things to Consider:

Low water level -- If you need to fill up your tank because the water levels have gone down, add some bio-safe to your tap water beforehand to ensure it is safe for your fish.

Not just aquariums -- For those that have betta fish, bio products can be added to small bowls as well.

Rapid results -- Bio products work rather quickly, so you don't have to wait too long to add your new fish to the tank.
