Ph probe - stray current

Why is my pH probe releasing stray current in to the tank?

It's most likely the other way around.
You already have and it's just closing the circuit.

when i remove the ph probe from the tank and i touch the water I dont feel anything but when i put the probe into the water and i touch the water I feel a sting, if there's already stray current as you say in the tank, not from the pH probe, then I would feel a sting if I touch the water regardless of whether the pH probe is placed in the tank or not cause the current would be flowing from the water through my body to and to the ground.

Is it reading correctly?

No i had it for 2 yrs then it started giving wrong reading and i couldnt get it to calibrate but it wasnt leaking any current at that time so i kept it in the tank until i plan to order a new one but now i got it disconnected cause of the current

Yeah, probably signs that needs replacement.
