T5 Retro... which bulbs?

[Rychek]

I'm having a bit of trouble with my IceCap 660 ballast and my GFCI. Every time I try to plug it in/turn it on when it's cold, it trips the GFCI. If I plug it into a non-GFCI outlet and let it run for a few minutes, then plug it into the GFCI, it works just fine. Anyone ever have something like this happen to them? I'm using a single plug GFCI that I picked up from Home Depot a few weeks back and a Coralife surge protector/dual timer. TIA.

what else are you running on that gfci with the lights?

I'm running 2 ~300 watt heaters (primary and backup), Koralia 3, CSS 65 skimmer, Mag 9.5 return pump and a small (~10 gallon rated) air pump. However, it still trips the GFCI with all of the pumps off. I'll have to test it with the heaters unplugged because I can't remember if they were on or not.
