A fish store guy suggested that I add a jet to my 32 gal. tank in order to move the water around and said that the fish actually like having a strong current but it seems a little excessive. My sand blows all over the place and my poor tiny firefish looks like he's caught in a tornado.
I've just been putting it on for a couple minutes at a time a few times a day in order to move any old food or debris, but I'm not sure if this is disruptive or helpful.
So, do fish like a lot of movement in their water?
Thanks.

I have a 4 foot FOWLR tank and I use my Eheim spray bar and a turned down large powerhead to circulate the water.
I normally have them facing the front or the back of the tank and that creates a nice circulation that gets behind my LR as well.
Your fish will let you know if it is to strong or all in one place by the way and where thet swim.
You basically don't want any dead spots in your tank.

Have fun

A jet, as in a fixture on the outlet of your filter, or an additional powerhead just to add circluation?

You might be able to redirect the flow to bounce against a back wall immediately, that would break the force of the flow.

I added a powerhead to my 29 gallon which has a Fluval 303 canister filter. The fluval uses no spraybar, the outlet is simply a 90 degree just below the surface to flow along the back wall fo the tank. the return is immediately below so the current goes all the way around the tank before reutrning. The powerhead helps circulate that first lower corner that is a bit still otherwise. But, no place is strong enought o disturb anything, you have to watch to see the flow.
