This is the reactor I am using.

The best one is the MTC

My setup:
Air is supplied by a Tetra Luft pump through a 500mg air drier, into a Red Sea 200mg/hr ozonizer and redox controller, then into the pressurized ozone reactor. Tank water is fed into the reactor from the main pump return and the output is scrubbed of residual ozone through a MTC SR-14 substrate reactor filled with carbon before returning to the sump.
