Tanning Ledge/Beach Bubbler/Fountain Suggestions

[ValAZ]

We've got a ledge with a bubbler (return) in it ... It's 18" deep. There's a threaded fitting in the return, holding one of those round, adjustable nozzle-things in it. (got the plumbing lingo down, don't I?)

It's flush with the plaster and gently bubbles up, which is nice, but it's more of a "water disturbance" than the bubbler I thought it would be.

Yesterday I unscewed it, took the round piece out and stuck in a 10" piece of 3/4" pipe. (I think - it was a scrap piece that fit!) Now that's a bubbler! My 4 year old loves it! It's easy to put in and take out.
