Do You Give Your Fish a Break?

I do not. Never really thought about it
My current builds up throughout the day- starts at a pulse ~ 30% power, then builds until 60% by mid day and becomes a constant flow, till it dies back down and returns to pulsing. Just a personal preference

Does the ocean give fish a break? Not being a smart ass. Legitimate question.
I think the currents change based on weather, season and tide

I may need to make my flow more dynamic in that case. Thanks for the question and info.
Another good question: is low flow good in the first place? Does that apply for all fish?
Im in line with everyone else, i dont want the flow to stop. And i have observed fish finding seemingly calm spots to sleep.

I think that’s the thing- as long as the fish have a calm place to escape the current and aren’t being blasted 24/7, it should be fine running constantly

The thinking was there is a lot more opportunity to find a calm spot in the ocean than in my 4' tank. There are only 3 fish in there at the moment, so I am probably over thinking it!
You may be thinking backwards. Because there is more opportunity, things are harder to find in large areas than small ones.
I think if you were to apply the hairy ball theorem to a volume rather than a surface area, you would find similar results. In other words, there is guaranteed (or at least practically guaranteed) calm space in your tank. If so, its probably easier to find such locations in your 4' tank than in the wide ocean.
...now if the goal is to find a large quantity of dead spaces, the ocean has more opportunity than your tank, so its more likely to find 1 million dead spaces in the ocean than in your tank. But if you only need a limited/small number, then your tank should provide the easier solution.
Of course, we'd have to dive a bit deeper into fluid dynamics for a more full explanation, and use modeling that incorporates the irregular shapes of rockwork and friction between bodies...
TLDR; a lack of calm spaces in an aquarium should be a non issue.

Lol @ ActiveAngel…no, no fluid dynamics please. Still trying to wrap my head around reefing.
Lol, i wasnt really offering. Just stating that diving into fluid mechanics, even at a basic level, is the next step. But i appreciate itAu contraire, I want to see @ActiveAngel 's modeling data and maybe a video tutorial
But maybe later. Im currently up to my neck in nutrient uptake and biomass modeling at work these days. Its a lot.

Biomass, I have too much of that or so my Dr. tells me.

It wouldn't be a response from @ActiveAngel without some crazy science.
I am seriously considering changing my user name to Hairy Ball Theorem.
