Thanks for that, I have two heaters in the tank and whenever i turn everything off and only have either one of the heaters on I get a shock so its definately them.
The heaters are only 1 year old, how long are they supposed to last and can anyone from the UK recommend a good quality heater?
So I take it a grounding probe wont work in this case then coz its only earthing the high current straight onto some metal and really wont solve the problem.
Anyway any help or advice on the heater thing would be appreciated.
Thanks
