I am trying to replace impeller on an odyssea power head and cant seam to find odyssea on line .Dose anyone know if they are made under another name or have inter net site.
Odyssea is a import knock-off brand. It's highly doubtful you'll be able to find replacement parts. The web site you bought the powerheads from is probably the best place to start. They do also go under the brand name "Jebo."
Or... take this opportunity to upgrade to some nice powerheads... Maxi-Jet is a wonderful powerhead and they do not cost too much.
