that is the model i've got in use on my 180 right now, works great. the seller is less then desirable about emails/replies/knowledge, but the product was as expected and works perfectly. keep in mind that it does NOT have a drier on it so the actual output will only be around 150 mg/hr tops. i'd still recommend a controller with it or any O3 unit.

just curious why you think this is more related to reef discussion then filtration? O3 is IMO a filtration question and the 'lighting filtration' forum was appropriate. just curious.
