Flow rate

Guys
Does 80x turnover seem excessive, it’s a mixed reef , usual pattern softies on the bottom sps at the top
Euphyllias , nems sway , can’t see their mouths or being battered around
Flow is not directed at any corals just circulates around everything
2 x 8000 lph on pulse 0-8000
1 x 12000 gyre again 0-10800 (on 90%)
1 x 5000 return - 2 bends so let’s say 4000

It’s 400 ltr and I ponder that using pulse mode as above you should maybe half the turnover cos it’s not constant
Hmmm thought's please

Got a video of the tank? It seems excessive to me but it also depends on how it all is being directed and where.

20x soft
30x lps
40x sps

General guidelines

For reference I have an SPS dominant mixed reef and my MP40s only max out at 28% intensity.

If your corals are happy then what works for you, works for you, don't worry about it.

I’ll pop one over soon mate

Only just ramped up from 65x so I’ll see if it changes
Maybe increased o2 does some chemical change?

Still, the question remains
If using pulse should you half the turnover amount

Ph is up from 8.3-.8.4 with the extra surface movement

So need all of the above haha

It doesn't look like your current flow is overkill to me. Nice tank! :)

It's kind of what makes mixed reef challenging but also having the right par levels too. I started out running higher flow but learned our little glass boxes really don't need that much flow at all to be highly successful. I also think high flow contributes to seam failures because people blast continual bursts of water energy against their sidewalls and after a period of time fatigue sets in and seams fail.

I have to say I've never calculated flow on any tank. I'll watch softies and some LPS for movement and how they react. Sticks I just watch how food blows around when I feed. Not scientific but works for me.

Oh.....That is a good point. Makes sense. Never considered this. And this is why I LOVE this forum. It's all the little bits of knowledge one gleans from others!
