which pump?

I am going to use a rio pump for my return. I was wondering which one I should use. it will be submursed in my sump. The overflow box i will use is rated at 300 gph. Wich model rio should i use?


might wanna do a couple searches on rio on a couple of reef forums and see if u still wanna use one.
Ive had rio's on my sump/skimmer for my 125 for about a year now. Never heard anything about this... I'll look into a mag though...

Mag Drive is a really good pump, energy efficient, cheap, and reliable, I have 7 of them, some of which have been running for 5+ years. Had one rio, and it melted down in my sump :mad:
