Shultz and I have found our new home... it's older and the electrical is not grounded(2 receptical instead of 3). So, here is the question: What options do I have as far as setting up my tank? It is a 120 gl(lit by 2- 250 watt metal halides and 4- 65 watt compacts), LED moonlighting, with a 55 gl fuge(55 watt RSD), a 55 gl sump(skimmer and auto top off), runs a calcium reactor and a kalk reactor as well as an ozone reactor. There are 2 return pumps(1- 700 gph and 1- 900 gph) and a 300 watt heater. I also have 2- 6" fans, a ORP controller and a ph controller, a wave maker w/4 power heads, and lastly... I intend to add a 20 or so gl gravity fed refugium above the aquarium. LOTS OF ELECTRICITY, I'm imagining! Can I get by with just a GCFI, or will I need to re-wire that 1 socket to a ground, or any other suggestions? Any help will be greatly appreciated.
