As I was completing the light
rack for the glass reef, I realized
that I had not planned for any kind
of "moon lights". Although I think
many reef keepers have blue LEDs
installed in their canopies because
they like the look of the dim blue
light after the main lighting has
been turned off, I have always felt
that there is no need to keep a
reef tank in complete darkness.
I suppose one could argue that,
in nature, moonless nights leave,
even shallow reefs, in darkness.
Still, I think most of the creatures
we keep in our tanks are "thankful"
for a little light to see by.
Since I already had (at that
time) the Aqua Controller III
Pro from Neptune Systems, I
decided on the Lunar Simulator
Module, also from Neptune:
- High intensity LEDs with
a wide angle lens (100+ degrees)
to provide the best possible
- High reliability direct
wired control connection to
the Aqua Controller/Apex.
- User configurable maximum
- User configurable control
- The Aqua Controller (and
Apex) dims the LEDs in phase
with the true lunar cycle.
- Can be purchased with 2
to 5 LEDs.
- 2 mounting holes on Lunar
Simulator and LED modules for
Because my tank is 8 feet long,
I chose the model with five LEDs.
I definitely like
the way the tank looks when the
LEDs are on.
Here's a pic of the lights after installation in the light rack.
Just a note: I quickly found
out that, although being able to
control the moon light in phase
with the lunar cycle sounds like
a good idea, in reality it doesn't
make much sense (at least not to
me). Half the time, the LEDs are
on during the daylight hours - yes,
just like the moon is often in the
sky during the day. The other half
of the time, they're off at night.
I suppose this functionality
could be of use if you were
trying to get your corals to
spawn by imitating the lunar
cycle, but for me - just not my thing.
