Will Moleaer nanobubble treatment cause oxygen supersaturation and harm fish?

This is extremely unlikely from Moleaer treatment alone. The ecosystem's oxygen demand far exceeds what any practical injection rate can supply. In waterbodies with existing high algae loads, daytime photosynthesis, not nanobubble treatment, is the primary driver of any oxygen supersaturation. Moleaer employs safeguards specific to such conditions, and no acute or chronic toxicity impacts on fish have been observed across deployments.

If anything, the evidence points in the opposite direction. Moleaer's technology is actively used in commercial fish farming and aquaculture facilities, where it has been shown to improve fish welfare, survival rates, and rearing outcomes. The same technology trusted to protect fish in controlled aquaculture environments is what's deployed in surface water restoration, a meaningful indication of its safety profile.
