Replacement Impeller for Sicce Syncra 0.5

This is the correct impeller for the Sicce 0.5 pump. The problem is the fact that I had to purchase it. My Kalk reactor came with this pump for the stirring pump, and in less than 1 year I have had 2 impellers break in half. Sicce USA replaced the first one, refused to replace any more, in spite of their 3 year warranty. <br><br>Zero stars for reliability. Five stars because the pump is silent and works well - when it works. Yes I bought another one rather than re-plumb my reactor. <br><br>I would not recommend Sicce pumps for Kalk reactor use.
