We have noticed we get a tingle when in the water close to the light and then on the other end with the rail at the steps. An electrician is suppose to come out this weekend to check things. Our light hasn't worked correctly since it was installed so I'm thinking it has to be that. However, with this electrician telling me to remove the ground to see if the current is still there because it should be bonded, I'm not very trusting at this point. Is there something I can put in the water to test or keep an eye on any current that may be in the pool? Just for safety sake? I found something called Shock Alert but I dont know how well it works. Any suggestions?
