luckyfish what do you mean when plugged in the right way? isn't sunsun pump got only 2 wires live and neutral?-- why do you have to replace it? is it faulty
Many people in the 80s -90s felt that lateral line disease was related to stray voltage but since then various nutritional, carbon use and even parasites have been linked to it too, definitely makes sense to ground an aquarium and i do believe titanium wire is the best option for the job long term.
and it looks like this company in cape town sells titanium rods and/or wire for medical use inside people's bodies so sure to be good enough for your aquarium http://www.titamed.co.za/download/Titamed_Brochure.pdf
Dont expect titanium to be cheap though but i honestly think everyone should ground their aquariums
Shawn, as Keith (nemosjanitor) explained, the leackage is depending on which way the pump is plugged in, between earth and neutral or earth on live.
What I still cant understand is, why is it, that all submerged equipment comes without grounding prong?
I Germany I used ATK return pumps. They are external only and driven via magnet.
The impeller housing is totally closed, no shaft or wire goes in there.
The two aqua medic returns I used for my big tank where also grounded.
It would be really interesting to know, how much stray voltage each member messured and after grounding the system, if there are any improvements become visible.
Improvements, like less algae, less stressed fish, better coral growth, etc.
It seems, I'm the only one here, who comes up with facts how much Voltage I had.
I wonder why!
