I am selling my used Nero 5 power head. It’s approximately 2.5 years old and I am the original owner. Asking $125 for the unit. I just put it in a bucket of vinegar to try and clean the coralline algae off of it. It comes with the guard to prevent any fish getting sucked into it. Once I clean it up I will post more pics of the actual powerhead. It works great and I’ve never had a problem with it.
