20 gallon cube flow

[shadow_k]

Hey guys
My question is has any had any luck putting a good amount of flow for 20 cube that’s gonna be LPS/softie tank and the best placement for the wave pump. Right now I have it right side glass same side as return slightly pointed up on pulse mode.
I have a jaebo 0w-10 but I always feel like my hammer coral does not like it. Can anyone point me in the right direction? Should I get a different pump I was looking at the Nero 3 I like how I can set a schedule with it but idk I’ll include pics of my scape and what my hammer looks like

About a third of the way down pointed slightly upward for surface agitation

On the right side or left ? And In the middle or corner. Sorry for all the questions And should I keep it at pulsing mode

I'm not familiar with cubes. On my 90 I have one at either end pointed at the opposite side. You want enough flow so there are no dead spots, while not kicking up sand.

I hear ya , I got a cube because it was a great deal lol but since it’s not long the flow hits the wall a little harder I think

Starting out I was always worried about too much flow. Now that my tank has been up a while I worry I have it too low.

Do corals adjust to flow like they would light ? I’m curious to know the funny thing is my Kenya , Xenia and zoas love the flow I have now but the hammer is just ehh
