Random Flow Nozzle

I haven't tried one myself, but I'd be interested to hear if they work as claimed. If you've got access to a printer, why not give it a go and report back with a review? There are .stl files here.
Some research on YouTube indicates that the printed models people are printing don’t seem to work as well.
 
I like my spray bar but I’d like to eventually go to something less intrusive in the tank
So long as I have flow in all parts of the tank I am happy. It doesnt need to be random.

To me the spray bar works.

I suppose placing the spray bar on the back bottom of the tank spraying up could work nearl as well at inducing circular flow. Once it gets to the top it only really has 1 direction to go…. And at the bottom it would be less visible… but at the cost of inconvenience of servicing it.
