Thanks for the advise, I went out and bought 3 more 15 amp GFCI's(total of five separate protected zones), so the heater/controller, half the k4's, other half k4's, return pump, rest of support system(skimmer, ca rx and sump lights) all on thier own dedicated GFCI. At least if one pops not everything will go down. After hearing Duanes story I took my thermostat/fan system off the GFCI as none of it is in or in danger of being in contact with water and would really hate the small room to get baked if GFCI were to pop.
