Red Sea Nano Reef Matt

[PatricioLG]

I have had the Nano mat for about 3 weeks, I have advanced it 3 times, the lights are on and it gets dirty, when it’s quite dirty water seems to edge its way under the 4” sock seal and spills over. I am using it in an Aqua one Reef sys 180. It has not auto ran once yet. Any suggestions please everybody

I have a 500 so I'm not familiar with the nano mat. Looking at the manual I would say make sure the auto advance is turned on, if it is I would make sure the sensor is installed correctly. It should advance when water reaches the sensor. If water never reaches the level of the sensor I think water has to be bypassing the fleece at a pretty high rate.
