OBIO Aquarium Water Treatment
This small bottle of OBIO arrives in the branded box that they show in the listing pictures along with the exact bottle. As others mention, I was hesitant as well to use this on my fish tank as I’ve never heard of this. I usually don’t use any enhancers or things that claim to help the water as it usually only ends poorly by disrupting the water chemical balance. So far, I was testing this on a small tank and this doesn’t seem to have any negative effects yet and I hope it continues to help the tank as the ingredients aren’t anything terrible.
