Spraybar for a Fluval 404

[markoshark]

I need to drop the current of my tank down a bit, so i'm looking to get a spraybar, and mount it 1/2 way along my tank, going to the rhs of the tank, and on the lhs the filter intake. Will this give 1/2 the tank high water movement, and 1/2 slower movement?

- trying to get the pantadon outta the corners of the tank

Or, putting the spraybar a fair way below the surface of the water, and putting it on the RHS of the tank, input on the lhs. If i do this, and therefore decrease the surace agitation, will I also need to put in an airline / bubble wall? (tank is planted).

Thanks.
