A long time ago I was at a fish store in Bellevue WA and the store had a big filter system that made use of spray bars.
I loved the look of the spray bar and so I asked about its use?
I asked if it ever plugged?
"All the time" was the answer the store guy told me.
The guy at the store said that cleaning the spray bars on the filters was a job they had tio do all the time, and that the spray bars would always stop spinning from time to time too due to gunking up at the joints.
If you have a pump that is strong enough that the spray bar never gets plugged then I could see this working.
If you get it to work, then try this idea-
Glue on that mirror stuff and turn the spray bar into something like a disco-ball and then have a few small pen size lasers aimed at the spray bar....
Then when you show the filter to someone have it inside a door to a shelf so that when you open the door the whole room lights up with light and reflected laser beams....thats a show!
