Generally if the turnover rate is around 20-30 times the size of your tank, measured in gallons per hour, it will be fine for LPS corals I think. It’s the SPS that really need high flow and are pickier about flow.
If you’re pumping out around 350 gallons of water per hour you should be good to go.
I love Frogspawn so I read your Thread.
The flow looks good. Watch when the Frogspawn opens up more.
They will open more when they want more flow or light, and certainly will close up when too much flow.
LPS with Inflated Tenacles are delicate creatures, and they can't be damaged (rip) with aggressive flow.
Once they rip, they can get infected and die.
Also easy to damage LPS if you are turning on and off flow AGGRESSIVE Flow.
What I mean is if you turn off the flow, the Frogspawn may relax, and they all of a sudden flow turns on and it get's hit to hard (No chance to close up).
Tank Turnover has nothing to do with Flow hitting a Coral.
(Yes the more turnover moves move water, but it's not really a factor for flow inside the tank, depending on placement and return pump output)...
Sorry Maybe the Comment is about the Tank type and 350Gal/Hour for that Tank hard setup is good.
Still it doesn't make sense to me.
One of my Tanks was nothing but LPS, and they like Gentle WIDE Flow.
(The power heads on left point around and away)
The Top 3 Colonies are Frogpawns (Greenish ones). Left is a Golden Frogspawn.
They all grew from one head like yours.
I them up and sold them and miss them so much , I just bought back a piece of my original back to grow again.
Some LPS can handle more, but in general they like flow that is not Rough or direct from a narrow stream.
This is my Tank now, and that Bubble coral (grown from a baby) is Extremly Delicate so I adjusted flow around it..
Putting those Pumps in Previous photo (at the Back). It was too much for the Bubble Coral as it got big.
On the Right is the Frogspawn I bought back.
One of my Ausssie Golden Torches (the one on left) did awful for a while till I reduce the Agressive flow on it.
Then it opened up and started to Flourish.
So your Frogspawn flow to me looks great.
A pump or pumps inside a tank pointing at a Frogspawn matters. (Look at it. Not caculate Turn Over Rate).
And NO FLOW is also bad, they need flow to dust them off.
They get stronger with resonable flow. Flop if they get too little.
