Well I treat with O3 before I pump the water into my res but not when my plants are in the same room. Ozone is extremely corrosive and is one of the strongest oxidixers known to man. I would be very careful with this one. Ozone is generated as a gas and is pumped in the res...that gas will escape and be exposed to the tops of your plants, not good.

I use H2O2....it raises the dissolved O2 quite a bit over a much longer period of time...Ozone does have its place though.

These are getting very affordable now with small aquirium units that work well for hydro... also increase O2 Now you can run w/o chillers utilize higher res temps for better root growth and nute/gas exchange, no chemicals... a must for large systems.. If you have ever had gnats or pith you know what I mean! FC http://www.enaly.com/OZX-200AT.htm Rating: 5
