remove the glass it holds in more heat than it keeps out, as for a 3' coil and air alone
probibly not, if you can get something colder running through that coil then definately
also larger fans will do better at heat removal than smaller fans (kinda duh :) )

hi.
Two points.
1, titanium tubing is a real PITA to bent, even if you get the softiest
grade.
2, the fact that the fan cools your sump is because of accelerated
evaporation. The evaporative cooling is what take the heat out of the tank.
With the fan blowing on a titanium coil with warm tank water, you might try
to cool the tank by blowing air on the front of the tank. It won't work
since it does not promote evaporation. You need to put the coil in some
cold water bath or something.

the only way I would disagree is in the part about "I have a new 125" if its going to be a
problem now when its *new* is the time to fix it, not next summer when all the sudden its
back up to 90F indoors, to many people complain about it down the road because they didnt
do something now.

I did leave out some important info in my original post.
I have a/c in my house and it is currently set at 75 (about 2 degrees
colder than before I had the tank), so the temperature of the room is
quite stable.
I have 4 power compact's of 96W each sitting on top.

I already removed the small plastic end pieces on the glass top
panels, so I do have a little exposure on top, but only about a 2 inch
wide strip.

I replaced the two large submerged pumps that were in my sump with one
external pump hoping that would reduce heat buildup a bit, it didn't
really seem to.

I'm not worried about replacing evaporated water because I'm
installing an automatic top-off system.

You are right, I would like to try as many different options now,
before there is any livestock in the tank.

Also, not sure if it's obvious or not, but this is a SW tank.

What tubing diameter you are thinking about?
If you never worked with titanium before
you should be aware, that bending thick pipes
made of it is not an easy task to do...

> Would this have any affect, or is the coil too small?

I have similar problem with my 30gallons reef - need to lower
down the temp only a couple degrees - I run a coil of compression
tubing (polypropylene or something similar, milky colour) and
use cold tap water to drip through it. Make some experiments
with it, if the tap water is not expensive in your area and using
it for cooling is not forbidden you could achieve this 4 degree
target doing the same.
