Not sure how that works, but I can't see an electrified heater, grounding the tank. A grounding probe is simply that, a ground, no electricity is run to it, to my knowledge.

No, I'm not saying use the heater as a ground, just as a precaution. If glass heaters have the potential to break and a titanium heater is unbreakable....one less thing to worry about. But, since there's still the powerheads to worry about...you will still need a grounding probe.

The danger is hard to quantify unless we get into some things that there really is not enough room here for.

First you can fibulate (sp?) the heart with as little as 10 mA of electrical current. Although low voltages are safer to work with all electricity can be dangerous when traveling through critical organs.

Grounding rods are a good idea and extra insurance for GFCI outlets & breakers. They will eliminate ground loops and give you a safe tank to reach into. I don't use them because all of my electrical equipment in or around my tank is run off the same GFCI breaker and the sensitivity of that device makes reaching into the tank safe. A GFCI breaker will trip when current below 10 mA (I think as low as 1/10 mA) is conducted through the ground. If I remember right the differential of current is also measured and if not within the same limits the breaker will also trip. Which means that the current delivered = the current returned through the neutral.

I have the Coralife (the first one). It's fine. I think the second one is the that fishfreek uses. Either one is fine. The first one just plugs into a grounded outlet. With the second one you need to unscrew the outlet cover plate screw, attach the ground wire and screw the cover plate screw back in. that would take about 10 seconds longer than just plugging in the first one , so either is a good choice.

HTH,

We have a very active African lungfish, who managed to bust his glass heater. The next day I was wondering, why he looked funny and as I reached into the water, I got zapped really bad. Now we have a titanium heater and "Eduardo" can bang it around as much as he wants!
