Hi,
We're trying to eliminate mold in our house as well as the greenhouse and fish house.
I have no idea if these are fish safe. It says in the directions "Use in an unoccupied space"

Ozone is a free radical and one of the easiest, cheapest ways to get cancer. It can also damage plant tissue at reasonably low concentrations.

IMO, if you can, you would be better off focussing on eliminating the cause of the mould, ie: Increasing air flow and reducing humidity.

Oh man! thank you Mr.Damage. No wonder it says use in an unoccupied space. As far as air flow this time of year I have the greenhouse closed up although unfortunately not perfectly. In warmer weather it has some corners that have low air flow, I have a little computer fan down in one corner to circulate air. I'll start figuring out how to get air circulating better through the entire space for this Winter.
Thanks again.
Brian

I'm still researching ozone generators. I looked on Monsterfishkeepers which unfortunately is a tumbleweeds forum these days. Some say ozone dissipates on contact with water. There also seems to be some type of device for mixing aquarium water with ozone gas, I didn't follow that thread though. This one from the EPA ins informative https://www.epa.gov/indoor-air-quality-iaq/ozone-generators-are-sold-air-cleaners
"How is Ozone Harmful?
The same chemical properties that allow high concentrations of ozone to react with organic material outside the body give it the ability to react with similar organic material that makes up the body, and potentially cause harmful health consequences. When inhaled, ozone can damage the lungs. Relatively low amounts can cause chest pain, coughing, shortness of breath and throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections. People vary widely in their susceptibility to ozone. Healthy people, as well as those with respiratory difficulty, can experience breathing problems when exposed to ozone. Exercise during exposure to ozone causes a greater amount of ozone to be inhaled, and increases the risk of harmful respiratory effects. Recovery from the harmful effects can occur following short-term exposure to low levels of ozone, but health effects may become more damaging and recovery less certain at higher levels or from longer exposures (US EPA, 1996a, 1996b)."

Ozone is used in aquaculture in conjunction with uv filters. They are very effective for bacteria but must have adequate ventilation and all ozone pipes cannot have leaks. Right now the injection system name escapes me and I don't have my catalog in front of me.
