Review on 🐠 Cast Acrylic Protein Skimmer: Ultra Quiet Needle Pinwheel DC Pump for 210 Gallon Saltwater Aquariums by Cheska Perry

The skimmer works great as long as it works. After a few months the pump started turning off and displaying "Err". To restore the pump control must be switched off. A few weeks later, it shuts down after a few seconds of operation, rendering it inoperable. Cleaning the pump doesn't change anything. Update 05/12/2021: The seller has not contacted me to offer a repair or replacement. The problem seems to be in the controls. I replaced the controller with a universal DC pump controller over a month ago (no thanks to the seller) and it's been working great ever since. I would rate this skimmer 4-5 stars were it not for the faulty controller. It is unfortunate that a great product can come with a poor quality third party part, resulting in complete user failure. By the way, reliable DC pump controllers are sold on Revain. A good example of low cost is the $16.99 Jebao SW-4/8/15 Wavemaker replacement controller.
