Tank Temps

I ordered some more slimline fans, but my temp still swings from 77 to
84 in a day. Is 7 degrees too much?

I was hoping to wait till next month to buy a chiller, but it seems like
I need to do something sooner.

I would adjust the heater so that it keeps the tank up to a higher
temp...like say 80 or 82 deg.......then the swing will be less
overall......84deg is a bit high, but IMHO is not really that far out
of line when you look at the online temps of various reefs of the
world. It is however a drastic reduction in fudge control if you run
into a situatin so you have lots less wiggle room if it was able to be
run at a max of 82 F. If you already have fans ordered I would just
bump up the heater a few degrees to reduce some of the swing, ,
install the fans and work at obtainig a decent happy medium of temp
with a bit of playing with fans and heater settings. Are you going to
use a variable power supply for the fans........A variable supply is
best as you can further control speed and noise levels of fan and have
more precise control available.
Most fans will run on 4.6 to 14 volts of DC power..

7 degree temperature swing can be stressful on your fine finned buddies.
Try and tighten up the temp swing +/- 3°F
Say 77°F - 80°F

Temp should be kept between 76°F and 83°F

My LFS actually advised me to set the thermostat on the heater to around
20C - this was to compensate for inaccuracies within the thermostat
itself...to prevent the tank from going too low if the ambient
temperature did...and to prevent overheating if the ambient temp was too
high....in a heated house that rarely falls below 70F and bearing in
mind the temp added by the lighting this kind of made sense to me - just
using the heater as a fail safe....of course I do not live in an area
where temps go that low for it to be an issue overnight...and personally
would not be comfortable myself if the temps in the house dropped to a
level that would really cause the tank temps to drop that
significantly.....some fluctuation is natural though...I was always
taught that it was sudden variations that caused a problem rather than
gradual changes....might be wrong though....

I have seen this issue debated on web foruoms for a few years. LOtsof
info one way or the other in regards to max temps and temp swings /
differentials. Iknow for a fact the water in th ekeys or bahamas cools
down consideranbly at night once that sun goes down and a tide
occurs........so fish do go through temp swings on a rather routine
schedule with sun up sun down and tide changes and storms.......it
happens. Same for max and min temps. I prefer higher temps and less
swing......I know person in the phillipines that runs his tanks at a
cool 86 deg, and he says that temp is pretty well common place for all
the reef and fish keepers there. 86 is not all that uncomon for aot
of reefs either around the world and there are even a few that are a
bit higher. As an experiment one time I ran a tank with just corals
in it at 86 deg and they did do fine, actually best they ever did with
a SG of 1.026 and 86 deg F, but I thnk its a bit extreme if fish are
at that temp. Yes they may live and do fine, but a bit more increase
could be a fish and shrimp boil too.

Pond and fish group[s area dime a dozen on the internet..just what
the world needs is one more, but if that one more is a momderated one
an dit works at excluding Tristan, then its well worth it......Having
Tristan in a group or forum is about like getting an outbreak of ICH
in a fish tank.

Two choices-

easiest - simply set the thermostat on your heater to 84. That's high,.
but not dangerously so (I run my tank this hot myself)

OR

Less easy - get a chiller with a dual stage controller.

Thanks. I'll do both and try to level this out.
