Need opinions on ViaAqua Acro-Cal Calcium Reactor

[RuGlu6]

Sorry i didnt know about this post.
I am using this reactor for almost a year, using gravity feed setup.
The only two things i dont like about this reactor are
1-Its small and requires friquent media changes.
2-The impeller shaft keeps coming out of the pump and i keep creasy glueing it back.

Now i gave up glueing it and just left it running with out the shaft, and its pretty quiet very quiet actually, but some times i dodnt know if impeller is rotating or not. Some times when it rattles, impeller needs a shake to re-start.

Thats why i thought about getting coralife 250 reactor for $135 at J&L.
ViaAqua Acro-Cal for 50$ i think it did serve me well and i would give it 3 out of 5. If only i could get the impeller shaft to stay in there this would be a very good little unit for small tanks or low SPS load
