grounding the tank can help avoid the power stress for the fish....
one of my powerhead got power leak and it stressed make my ivory developing blood clot at the tail base
when the tank is not grounded... when i removed the defective pump' it heals nicely....
then later, another pump broke down and leaked power. the presence of ground wire neutralized
neutralized the current and my ivory did not developed blood clot. when i removed the ground wire,
Ivory acted strangely and became stressed...
Ivory is pure white that is why any blood clot can be seen easily
a journey to a thousand miles always start with a single step,
all you have to do is move forward, aim, and respect the pathways
of others along the way.
