We run SeaClones at the store and they do alright. They will not, of course, pull as much waste as a Berlin or other high end skimmer...they just don't have the power. We sold a Prizm to a guy a while back and he has indicated that he is happy with it. He did say it was a little noisy...I've never heard it run and have no idea if he has it adjusted right. IMO
, the SeaClone would be sufficient for a 29. Wish I could tell you more
. I really doubt you would be disappointed with either one.
