"...since you are using a GFCI outlet/breaker (you are using one right?)"
No I'm not actually, you called me out. I did install them in my kitchen and bathroom and I did read several advisories to use one for aquariums but I just ignored it. I do use drip loops though. You did however inspire me to search for these things which are about the same cost as the hardwired versions so maybe I'll budget this in for all my aquariums:
But this thought is a total drag since I have 6 aquariums. Thanks a lot.
