Do Koralia's crap out?

[Toolman]

Thanks for all the help on my last problem also an attaboy to "C" I just noticed I am not pushing alot of flow from my Koralia. Do they loose power before they crap out? I gave it a vinegar bath about two weeks ago. If I choose to replace is a #2 big enough for a 29 or should I go bigger.:dunno:

Nope, I don't think they slow before quitting...they just up and quit. And depending on what livestock you're keeping will determine how much flow to have. I'm my 29gal, I have a koralia 1, 2, and 3, along with a maxi-jet. My 3 is behind the rockwork, the 2 is at the top making ripples, and the 1 and maxi-jet is mid level and low to the sand bed to keep particles suspended.
