Temp and IceCap?

[alrha]

Every now and then i notice the temp gradually drop and then come back (say from 81 down to 76 and then back up, slowly). I think it happens when my IceCaps are on or are coming on.
is this a known thing? or am i crazy?

Look at the data logs to see for sure. Make sure that your ballast and it's hood are grounded. Separate the ballast's cords from the AquaController's and coil them up to make them as short as possible.

i see the drop on the screen. my data logs are set to only record once an hour, so it likely wouldnt catch it.
the ballasts are up by the lights and the plugs come down to the DC4HD's in the cabinet (no extra slack). The ACjr is plugged into a different circuit than the ballasts. The only connection is via the DC4HD's.
