How strong I that powerhead in the top left?
It will say on the back of the powerhead next to how many watts it uses.
The surface still need roughing up as it still looks a bit calm. Lets say your tank is 100 litre so you need to be moving at least 1000 litre an hour that's 10x your water.
Looks like you have a candy cane coral, that's an Lps (large polyp stony coral) that needs around 20x water movement so I would aim at 2000 litre an hour.
My tank is 500 litre and I'm pushing around 20,000 litre an hour so that's 40 times and my corals like It.
