**Tell the Truth**

  • We are currently upgrading MFK. thanks! -neo
everything on for just hands. everything off for water changes.
 
leave it all on
 
All tanks should be plugged into a GFCI outlet. They range from $5-$25, so there is no reason for not changing out the outlet(s) that your tank(s) are on.

For low voltage leakage, you should have a ground probe. I made one for my largest tank simply by using a piece of 12g wire. I stripped about ten inches off the probe end and placed it in the sump. The other end was stripped about two inches, folded over and crimped, and then inserted into the ground slot in my GFCI.

All species of fish that are prone to Hole In The Head should have grounded tanks. Even though my tank was GFCI protected, I measured 1.7 volts of leakage when two of my fish got HITH.
 
To measure the voltage leakage in your tank, make sure everything is on, then using a multimeter, place one probe in the ground slot of your outlet and put the other probe in the water.

Could you tell me more about this, should we be worried about low voltage leakage, I haven't heard much about it, any info would be nice.
 
I hate turn anything off for this reason. (by anything I mean everything I own)

I have only 1% of the time seen something burnout, break, or shutdown, while it was running; on the other hand 99% of the time stuff breaks when powering on or off.
 
The only thing I unplug is the heater during summer.
