Neptune Apex Causing my Light to Flash

[abcha0s]

This happens to me too!

In my case, the MH ballasts are connected to a DC4 and everything with them is fine.

Connected to my EB8 I have things like: CO2, Fans, Sump Lights, Cabinet Lights, Tunze ATO, Etc. Generally smaller equipment.

Ocassionally, I get what appears to be a surge or a spike through the EB8 where some or all of the devices seem to flash. The sump lights are the easiest to see, but I sometimes here the clicking of the CO2 solenoid.

The behaviour does seem to have a trigger, I just haven't figured out exactly what the trigger is. I notice it most frequently after a feed cycle when certain pumps start back up, but this correlation is inconclusive.

Honestly - I absolutely love the functionality of the Apex, but I have concerns about the quality of the hardware. I've just sent some hardware back to Neptune to be replaced.

I had exactly the same problem. Do you have a low voltage appliance plugged into one of the regular outlets on the EB8? That's what was doing it on mine. I just plugged my 12v fan into a mechanical relay'd outlet and presto no more problems.
