Wave maker - Night Mode ?

[hiepwan]

I Just bought a new wave maker have night mode. So does this night mode good for fishes and corals ?

During the daylight, i set the flowrate 90-100%
During the night, i set the flowrate down to 40% so fishes and corals can sleep, rest...

I know in nature, wave never change and always strong. So if i set the flowrate low, does that help for the fishes and corals?
In theory, easy flowrate, the fish can rest better. But i am not sure how's about corals.

Has anyone haven't use night mode but both fishes and corals are well?
Has anyone tried night mode and have a better result than normal mode?

I know some people lower the flow at night. I never have. I don't think the ocean does. I think its something that makes us feel better more than the fish. Whatever your preference is.

I've done both...found I had better coral health and growth without changing flow during night.

With my old 90g back in the day, I never varied my flow. I had it on set it and forget it.

In nature there is a difference between day and night tidal and wave actions.....
I use night mode also...drops to 45%

Our captive tanks are not the ocean and in many cases should not be treated as such.

Coral tend to expel waste at night and many other biochemical processes use oxygen during lights out. Fish tend to sleep in nooks and crannies with already low flow. Lowering flow overnight can create all kinds of issues, especially with oxygen levels.

Ramping down a bit from the peak of the day is fine, but it is easy to quickly pass a critical threshold, or hover right near one.

So....anyway.....

That does not mean that you should replicate that in your tank. I indicated why.

The raw water flow over a reef, even at night is insanely different than your captive tank where the same water is must moved around. Two very different environments.
