I just got a CPR HOB fuge sent to me for b-day, but I'm bummed that it came with a RIO pump (why do they use those?) and I get alot of bubbles coming out of outlet.
What would be the best replacement for the pump, and what would be a good mod to decrease bubbles?

Mini jet 606, (159gph)

Or Maxi Jet 900(200gph) or M.J.1200 (295gph) depending on how much flow you need.

They are made by "Aquarium Systems" and are good long-lasting pumps that produce little heat

Oh, and CPR makes bubble traps.

But I'm sure you could catch those bubbles yourself by cutting a piece of sponge filter media and placing it inside the return tube. You would just have to rinse it out on a regular basis so it doesn't get clogged and overflow your fuge.

I'm sure someone else will chime in another idea.

hope that helps some.
