This is my tank. Powerhead is in upper left corner... there’s a bad dead zone right below it where those 3 corals are. Where should I put it? Should I get another one?

13.5 gallons and it’s 265GPH
I would think adding another small powerhead opposite size of tank would be best option... anyone agree or disagree?
I have yet to see the tank that can’t benefit from two or more power heads. IMHO they are best placed about 1/3 of the way down and angled up and in towards the center.
What size tank? You should aim for 30x + for in tank circulation. As an example, my 120g SPS dominant mixed reef uses 2 x 250 gyres, 2 x koralia 1500’s on the back and a single koralia 1150 on one side that is there just to prevent dead spots behind the rocks. I figure total flow is ~ 60-70x

Totally agree. Not only will it give you better flow, but should also break up the continuity of flow, giving the corals a little more turbulence. They just love turbulence.

So I should put it closer to the bottom?

I personally would try a couple different locations on the right side of the tank. See what works best with your aquascape and coral placement

A practice I have when checking water flow during my tank cleaning is to blow off detritus from the rock with a turkey baster & seeing how detritus moves in order to check if my pumps need cleaning, replacing or redirecting. It will also show you where the dead spots are by observing the detritus move throughout the tank & spotting areas where it remains suspended, that would be a dead spot. If there is a dead spots, it would be best to place a power head opposite to that area & aimed at the dead spot but making sure it doesn’t interfere with other power heads flow. Hopefully that makes sense & it helps.
