Turning Flow Down at Night

[ElementSquaredLLC]

In my 200 gallon penninsula tank I have an AI Orbit 4 on one and and two AI Nero 7's on the other. The orbit 4 runs at like 70% during the day while the 7's run at around 50%. The tank is 6ish months old so none of the corals are very big and that whips them around pretty well. Have been experimenting with turning the flow down to a constant 25% at night. Anyone else do something like this or leave flow the same during the night?

Welcome!!!

I also turn flow down at night.

Yes. Lower flow at night. Have zero idea why except that is general what happens in nature.

No it doesn't. It depends on the Tidal Charts. Fish, inverts and the biological filter still need that extra oxygenation and flow regardless of time of day

Haha. Ok it is common knowledge that all things being equal, reef environments experience less tidal force at night.
