I haven't tried the nozzle spray, but I can say that the spray bar on my filter works perfectly - to perfectly! It's producing to much of a current for my fish! There is an outflow regulator that you can use to adjust it, but mine's broken. I'll be taking Nielanh's advice on connecting 2 spray bars together. I think my fish will be much happier with that!
