Under gravel jets?

[CharlieTuna]

Under gravel jet systems seem to get a lot of love on other fish forums, but not much here. I'm contemplating setting up UGJ's from the output of my canister filters for my 210g. Any thoughts on the UGJ's?

There is a thread in this section all about them, let me see if I can dig it up.
