Not sure how, but seems like someone (prob urchin) chewed through my Nero 5 and exposed the white and blue wiring. Hoping not to fry my tank, would electrical tape be safe to use? Might consider upgrading to an MP10 (as this nero 5 is in my 50gal and never goes above 20% power) and prevent wires from going into the tank but other than this, the pump runs great so I’d hate to toss it over this issue as it was pricey.
Thoughts?
