FAQ
How does the +O2 function improve aquarium water quality?
The +O2 function releases activated super-oxygen (O2-) that enhances bacterial activity in the filter, leading to more efficient breakdown of organic waste and improved water clarity.
Is the Substratpro+ Oxygen suitable for both freshwater and saltwater tanks?
Yes, the Eheim Substratpro+ Oxygen is pH neutral and suitable for both freshwater and seawater aquariums.
What is the bacterial settlement area provided by this substrate?
The substrate offers a high porosity of 45%, providing an above-average surface area for filter bacteria to settle and thrive.

I’ve used the Substratpro+ Oxygen in my freshwater tank for three months. The water has become noticeably clearer, and I see more active filter bacteria. The oxygen boost seems to help with fish health and reduces algae growth.

The substrate fits well in my tank and maintains a stable environment. I appreciate the neutral pH and the fact it works in both fresh and saltwater. It’s a bit more expensive, but the results justify the cost.
