How would CaCl2 (aq) + NH4OH (aq) react?

It's for a precipitation procedure in heterogenous equilibrium. I've searched and found that these are actually products of Ca(OH)2 (s) + NH4Cl, so I'm more confused. In the experiment, there was no precipitate after centrifuging, and 4M NH4Cl was added to the mix. (Actually, if this reaction were in equilibrium, it might have been easier to explain... but... yeah, apparently it's not.)
