only problem is you can't use a grounding probe and a GFI togeather or your equipment will be always tripping. unless you have absolutly no voltage leak which.

A GFI is enough to protect you, other wise code would require us to have grounding probes in our sinks as well as close outlets haveing GFI breakers.

Sure you can, running both for 4+ years and have only one trip.

thats cuz you don't have any leakage. Grounding probes don't solve the problem they hid it, a GFI is realy all you require and if it trips you have a problem.

I split my equipment up between 4 GFI's my self I ran two heaters two MH lights and two actinic ect all set up on different GFIs. this solves the problem if one trips you don't lose everything.

Though they say a GFCI will trip fast enough to protect you still rather it trips on a ground probe than using me as the path to ground.

Thats the purpose of the GFCI it trips before the electricity uses you as a path to ground.

May be 1/2 a cycle but the comparator cct needs to see the imbalance, that's through me without a ground probe

If the fault is in the light and the ground probe is in the tank, then it is still through you.
On a side note a GFCI must trip at 0.006 Amps so I don't think 0.0059 Amps for a time of 0.0083 will be of any concern.
Plus the ground probe is a lower imperdance path to ground than any other possible path for the current, and lower impedance means higher current.
