if ya use a rio ya better
just pitched one after a year of use but would get shocked bad trying to start the pump
also my other tank running 2 mag drives a 3 maxi-jets i would feel a bit of a shock not as bad as the tank with the rio but added a prob anyway and no worries now when putting hands in the tank
but the tank with the rio the fish now act wierd after that and the grouper which used to hang out under the rio wont go to that side of the tank anymore ?? not sure if it has caused any serious issues or not ?!?!?
