which water circulation pump

[chansman]

I picked up a RSM130 over the weekend and need to add some flow. Do you guys like the Koralia nano 425 or the Tunze nanostream 6015 better?

I find the tunze pumps to be more reliable. If you can afford it, i recommend purchasing the Tunze

I'm 90% sure I'll get the Tunze.
