Has anyone ever used these powerheads from ebay? They look like a Koralias, I contacted the seller and asked the brand name. He replied "they are OEM without a brand name" Anyone have problems with them, or success?
When I first got in the hobby I bought some. They were griech brand 1300 gph. I used them for a year but made sure to have a grounding probe. Never had any issues outside of them not starting in the right direction all the time when plugged back in.
