I can absolutely positevly confirm that this unit is not adjustable.
I got one from Ocean aquatics. Used for one day on my 60 Gal and returned it back to store.
My ORP would jump from 250 up to 450 in 15 minutes.
The switch will only turn the unit on and of thats it.

I have 2 units purchased a year apart and another reefer on another board has also confirmed that the potentiometer which is supposed to adjust the output is not connected to anything. The unit runs full blast at all times.
(the 2 wires goint to the back of the pot are for the on/off switch)
If you are running this on anything but a large system and without a controller this could be very dangerous to your livestock and not very good for your health.
here is a much better pic taken by another reefer of his unit

I would like to get feedback on how many others have this same problem and to alert others who may not be aware of this problem. |
