Description	It is shown that standing wave is unstable if we consider four wave nonlinear processes. We compare numerical simulation of instability of weakly nonlinear standing waves on the surface of deep fluid in the framework of the primordial dynamical equations and in a laboratory wave tank experiment. The instability offers a new approach for generation of nearly isotropic spectrum using parametric excitation. Direct measurements of spacial Fourier spectrum confirm existence of the instability in a real life conditions for gravity-capillary surface waves. This is a joint work with Sergei Lukaschuk (The University of Hull, UK).
