For the airstone I'd place it on the bottom next to or in the dead spot. For a powerhead I'd place it where it's convenient but have the current it produces pointing towards the dead spot in the aquarium.

Should I just get a weak gph power head or a high gph powerhead? This is for a jardini amd a pleco fish

I'd suggest adding a powerhead, placed near the bottom; however I'd try to angle it at the same direction as your other outputs, you don't really want conflicting water flow in the tank, can make fish uncomfortable

My 1.5 " cichlids swim in a 500 gph flow spread 8" wide. 1" pvc pipe with six 1/2 holes.

A $20.00 adjustable submersible pump. 400 gph. Just an idea.

An under gravel filter plate with water pumped under the gravel.

IMO, I had/ have a " dead spot" no oxygen under the entire bottom of my tank. Used it to reduce nitrates, in an emergency situation.
