I just found a nice rio 2500 pump in a box of inherited equipment, and while looking it up am seeing some horror stories about rio pumps(or at least certain models?), from electrocuting everything in the water, to burning out/melting/cooking the tank. Does anyone know about this? Does anyone know where it would say UL listed on the pump, if it is? Sadly I realize that I had also bought one(haven't used it yet) awhile back because it was what was pictured with the Berlin X2 skimmer I have (not used yet), that after a long time of searching and emailing, even the Red Sea company, couldn't find a single word anywhere about what kind/how strong a pump to use with the skimmer, and eventually figured out what pump was included in the "pump included" box. Now I'm really worried about using them, brand new or old.
