I’ll reread my post but I don’t think I was trying to tell him how to do what he wanted to do, I think I was telling him what I did in my situation that worked.
@27 I was quoting speedskater who said, "Do NOT add other ground rods connected to other points!". I agree with that.

Yes, you can add as many ground rods, ground wires, ground plates or Ufers as you like, but they all need to be connected together and then one connection to the AC system at the main breaker box.

OK older posts's my situation.

I had an outside outlet box originally installed for a Pool which was left unused.
It's a 50 Amp 3 wire box mounted on the wall.

My Studio/Gym (50/50) is in a metal building about 60' from the house. I ran an appropriate heavy gauge underground 3 lead wire to the building and installed a Breaker Box.

I did run a heavy ground wire into the building from a 6' rod I rammed into the ground. The main house also has a grounding rod.

Will the ground coming from the house from the "pool" circuit be sufficient and should I remove the 2nd grounding rod from outside the studio?

the building code in my suburb requires that that a breaker box in a detached structure have an additional grounding rod.
(it would have continuity back to the main building ground rods thru the Safety Ground wire)
