I have many Koralias, both quite old (like 5 yrs) and new (a few months), and I have never had any reversing issues with any of them although I've heard lots of people complain about this. The only powerheads I really care for are Tunze or Koralia. MaxiJets have their place as mixing pumps or reactor pumps, but not as in-tank powerheads imo.
