I have a ClearWater Tech Microzone 300 Ozone Generator
And a PinPoint OPR Controller
Both were used for about 3 weeks.

Microzone 300 rated for 300 mg/hr and has a variable output.
New this unit sells for around $350
I will take $225 for this unit shipped.

The PinPoint OPR Controller is like brand new.
Not in the picture is the probe.
I loaned the probe to a friend and he is buying a new probe to replace this one.
These sell for around $190 new.
I will take $165 shipped.

Buy both for $350 shipped
