I agree. I encountered the strongest current in over 100 dives, during a
night dive in the Maldives. The fish all managed to find quiet places
amongst the rocks on the reef or in small caves etc. They do exactly that
in my tank.

I know what you mean. We did a little snorkling in Jamiaca and the amount
of water passing over those reefs is insane. We're talking about rooms
full
of water just sweeping by. I did notice however that the waves really
calmed down at night. Is it just a misconception that calmer surface
water
at night equals calmer currents underwater? I don't want to cause any
undue
stress for my fish during the night shift. I know more hiding spaces
would
be a great solution, but the finances won't allow an increase in LR at the
moment.

Thanks,
Justin

There is no case for lower night time flow in aquaria, I have logged 272
night dives and the currents are the same as in the day, yes there are
variations, but non more so than during the day.
Regardless of what water propulsion pumps you use to create flow in your
aquarium, none come close to just how strong real currents are on real
reefs.

I was curious to know how many people out there reduce the current
flow
in
their tanks to simulate calmer night oceans? I have a 240 FOWLR and
although there are good hiding spots in the LR for the fish to sleep
in,
I'm
afraid that once the tank is fully stocked, sleeping arrangements
will
be
quite tight. Also, fish size plays a part. I'm aiming at
Butterflies
and
Angels which get rather large.

Currently I have ~2000gph returned through two sea swirls 24/7. No
other
water movement in the tank. Just the Sea Swirls rotating the
returned
water
around.


I do not try to simulate clam night. I have several pumps. One main
[Mag

pump to keep the current 24/7 for 100USG. There will alway be water
return
from the sump and refugium. The others in the tank can be off or on
which
depend on my mood or whatever the reason. One main thing you need to
take
note is - try not to have dead-spot from anywhere in the tank.
